404 and 503 decoded: Here’s what those pesky internet error fails really mean

You can’t load a webpage you want, but those error codes are trying to tell you something. We’ll help you figure out what to do next.

It was Feb. 16 and I had two alarms set on my phone for Beyoncé’s Formation tour tickets. As they were bound to sell out in minutes, I was on the website, ready to refresh the page as soon as the clock struck 10 a.m. But when the critical moment came, the page only showed an ominous message: «503? Service requested is unavailable?» I refreshed the page frantically. What if I couldn’t get the tickets? Who knew when Beyoncé would tour again? But I got the same error over and over again.

I picked up my phone hoping to have more luck there, but I got the same message. Finally, after what felt like a bazillion refreshes and clicks, I was able to get through. There they were — the tickets I had been waiting months for. Whew! The purchase confirmation screen appeared and the nightmare ended. But I kept asking myself where that message came from. Was it something I did, or was the website just borked?

Those random-seeming website error numbers like 404, 503 and 301 you sometimes see after typing a URL can throw you off your groove or worse, ruin an urgent task (like buying Beyoncé tickets). Sometimes, like if you mistyped the URL, a simple text change can put you back in business. Other times, there may be a bigger issue — the server is down or there’s an internet outage.

To help you understand what to do the next time you see one of these online uh-ohs, I’ll break down the basics of those strange codes — even the ones that you might not be able to crack on your own. And if you’re fascinated by all of the code-lingo, you can always dig in deeper with a coding course for beginners.

404s and other common website errors: What they mean

Some website error codes are your fault (oops), but others are because of problems with the server that only the website’s administrator can fix. Chances are, you’ll see them with every refresh — it might help keep your annoyance at bay to understand why (but I doubt it).

404: One of the most common errors you’ll see, it means the page cannot be found. Nowadays, some sites will design its error code pages with cute puppies, links to other pages or a funny illustration to lighten your no doubt frustrated mood. Double-check the URL for typos and try again. If you’re typing the correct URL and you still have no luck, the page has been moved or deleted.

301: You may have heard of a «301 redirect,» but probably have never seen this code displayed on a site. Think of it as a smooth transition from one old URL to a new one, sort of like forwarding your mail. You should still see the webpage you wanted when this happens, but it likely has a different URL than the one you entered. It’s a permanent move, and even if you use the old URL, you’ll still be automatically routed to the new one. Bookmark the new URL for future reference.

400: This one is best known as a «bad request» for the user. On Google Chrome, you’ll get the message, «This page isn’t working at the moment» along with some guidance about contacting the website administrator. Usually, it’s caused by an error on your end. There may be a typo in the URL, the server may not understand your request, or the file you’re trying to upload is too big. Try clearing your cache and checking the URL for typos. If you have no luck, take Google’s advice.

410: This is the «Gone» status. You may see a message like, «This page does not exist,» or «Page deleted or gone.» There’s no problem on your end — you’ve got the right page, but the website administrator may have deleted it for good.

451: This code blocks you from seeing a URL for various legal reasons. According to a developer resource page from Mozilla (the maker of the Firefox browser), a person or organization may have made a legal demand to remove the content or the page may be blocked because of government censorship. You should see the legal reason on the page with the status code, but it’s not always guaranteed. If you’re determined to see the content, you may be able to get there with a few tech-savvy tactics — like a VPN or proxy server that acts as a tool to bypass the server’s restrictions.

503: You’ll likely see the message, «503 Service unavailable,» when a website’s server is down, so you won’t be able to access the site until it’s fixed. Reason being, the site’s server could be down for maintenance, too many people may be causing the site to overload, the site could have a bug or someone looking to cause trouble has taken the site offline. You won’t be able to access the site until it’s fixed so it’s best to try again later to see if the server issue is resolved.

200: This code you won’t see because it means that everything is OK. The site, its server and your browser are all working fine, so there’s no need to alert you there’s not a problem. The only place you’ll likely see it is in the code (or back end). In fact, most codes that start with a 2 are a good sign that the communication channel between your browser and the company’s server is working.

How can I fix website codes with images and videos?

It can be frustrating if you’re trying to play a video, upload or download media, but see error codes instead. More often than not it’s a user error, and it’s up to you to fix the problem. Sometimes you’ll see a small icon that looks like a picture in place of the video or image you’d hope to see. In that case, you’ll know something’s wrong.

If you get status code 415, it’s a red flag that the server doesn’t recognize the file type you’re using. Popular photo- and video-sharing sites will list the file types they support, typically on the Support page (here’s the list for YouTube). If yours isn’t listed, try converting the file to one of the approved formats before uploading it again.

Front end developer Allan Hernandez says that most common supported types are .mp3 and .mp4 for videos and .jpeg, .png, .svg and .web for images. If you’re uploading a video or image using one of the correct file formats, he says, it should be easy and error-free.

Another common problem occurs when you try to upload files that are too big for the server, also known as status code 413. In this case, it’s best to reduce the file size before uploading again.

Here are a few other common error codes you may come across with media and what they mean.

  • 404: The media file has been moved or deleted.
  • 403: The server cannot access your image or video — possibly because the firewall is blocking it.
  • 429: You may have sent too many requests without giving the server time to process them. So, if you’ve clicked «upload» a bazillion times, you may get this code.

Are any errors my fault that I can fix?

Yes, there are two types of code errors: client and server. Most client errors start with a 4. You’ll need to fix something on your end before continuing. For example, the 403 code may mean the page is forbidden, or the web administrator restricts access to that page. You’ll need to go to another page or site.

Usually, if there’s an error, you’ll need to do one of these things.

1. Restart your computer, modem or router.

2. Check the URL for typos.

3. Visit a different URL.

Sometimes, other actions may be required, such as you need to pay to see gated content or, if you’ve clicked a button constantly, you just need to wait patiently because the request isn’t processing fast enough.

If an error starts with a 5, it’s the server’s problem and there may not be much you can do. Try contacting the website’s support to let them know you’re getting a server error.

In a World Without BlackBerry, Physical Keyboards on Phones Are Making a Comeback

Commentary: You might not even need a new phone to get clicky buttons.

If you have fond memories of clicking away on the BlackBerry, the Palm Treo, the T-Mobile Sidekick or similar handhelds from back in the day, I have good news for you: Phones with keyboards are making a comeback. Sort of. 

There’s a growing number of companies looking to bring back clicky, tactile buttons, whether for that nostalgic appeal or to reinvent phone keyboards as an addition to your iPhone or Android device. Some of these have even just announced their plans at CES 2026 or will be bringing these button-filled phones to this year’s Mobile World Congress. 

From keyboard cases to modern-day BlackBerry clones, here’s what we know about the potential QWERTY renaissance. 

Why are keyboards on phones making a comeback?

It’s difficult to assess the exact turning point for when physical phone keyboards made a comeback, but we have a couple of guesses. Perhaps the biggest reason this is happening is that people rely on their phones as their primary computer. As such, they’re probably typing long emails or editing documentation with just their phone’s touch keyboard. 

While that’s perfectly fine for most people, some yearn for the comfort and tactile feel of physical keys. And perhaps getting tired of bad autocorrect errors when typing too quickly.

Another potential case for phones with keyboards is simply the desire for variety. Some people might feel a general fatigue over the familiar look and feel of modern smartphones. Having a handset that functions differently — see the popularity of recent flip and folding phones — is a welcome change. 

Plus, phones with keyboards appeal not just to the older generation who miss them, but also to the younger generation who are increasingly into retro tech. 

Can I get a BlackBerry in 2026?

Not really. If you want to get a new BlackBerry right out of the factory, you’re out of luck, as the company discontinued hardware production in 2020 and further discontinued its software services in 2022. 

You could try to get a BlackBerry on the secondary market (like the TCL-made KeyOne or Key2), but the Android version is outdated and won’t be as functional as other smartphones. Wirecutter’s Brenda Stolyar recently attempted to revive a Blackberry Classic Q20 from 2015 and discovered that, while it can still run modern apps, it takes a lot of patience to sideload them onto the device.

Zinwa is one company that’s buying up old stock of BlackBerry hardware, replacing the internals with new components, installing Android and then reselling them. Its first «product» is the Zinwa Q25, which is essentially a retrofitted BlackBerry Classic. You can buy the finished product for $400 or get a conversion kit for $300. 

What keyboard phones and accessories are currently available?

There are several options for keyboard phones on the market. 

Clicks keyboard case

The easiest way to get a phone with a keyboard is to turn your existing phone into one. That’s the promise of the Clicks keyboard case, which adds a physical keyboard to most modern smartphones. It made a big splash at CES 2024 and has continued to expand its lineup (we’ll get to that shortly). Simply pop your phone inside the case, and voila, you’ll have a phone with a keyboard.

In our hands-on, we liked the extra screen real estate, how quickly the keyboard interface worked, the preprogrammed keyboard shortcuts and the tactile keys. That said, the keyboard does feel a bit crowded, and it’s unclear if it’s that much more comfortable than the default touch keyboard. Currently, the Clicks keyboard case works with the iPhone 14 and newer, the Razr 2024 and newer and the Pixel 9 and 9 Pro. Its price starts at $139. 

There are also plans to release a Clicks Power Keyboard, that attaches to your phone via MagSafe or Qi2 magnetic connection. The Power Keyboard has a slider that accommodates phones of different sizes, plus it can be paired with a tablet, a smart TV or anything that uses Bluetooth. This makes the Power Keyboard much more flexible than the Clicks case, since it doesn’t need to be made for a particular device. 

The preorder price is $79, though that could go up in the future. 

Clicks Communicator

If you feel ready to get a dedicated keyboard-equipped phone, Clicks also recently announced the Clicks Communicator, an Android smartphone centered around the keyboard experience. It is designed by a former BlackBerry designer to show what a new BlackBerry phone would be like for 2026. It has a slimmed-down interface that prioritizes messaging apps, a text-based home screen and of course, a tactile and clicky keyboard.

As it’s not as full-featured as other modern smartphones, Clicks is positioning the Communicator as a secondary productivity-focused device, which might be a good thing if you’re trying to limit your social media screen time. 

It’ll be available later this year for $499, but you can preorder it now for $399. 

Unihertz Titan

Unihertz is a Chinese company that’s been making keyboard phones for a few years now. They’re all part of the Titan series and run Android. The current lineup includes the Titan, Titan Pocket, Titan Slim and Titan 2. Plus, an upcoming Titan 2 Elite has been teased for Mobile World Congress. It looks like a curvier addition to the lineup, compared with the other passport-shaped models. 

These phones look a lot like BlackBerrys of yore, and the Titan 2 in particular seems to bear a passing resemblance to the BlackBerry Passport. 

Prices start at around $300.

Ikko Mind One

The Ikko Mind One is a unique «card-sized» Android phone that comes with an innovative Sony 50-megapixel flip-up camera and, indeed, an optional keyboard case. It also ships with an «Ikko AI OS,» though it’s unclear how that works just yet. It looks utterly adorable, but we haven’t heard enough about it yet. 

The Pro version sells for $429. 

Minimal Phone

If you combined a Kindle with a BlackBerry, you might have the Minimal Phone. As the name suggests, the Minimal Phone is designed to be a super-simple distraction-free alternative to the modern smartphone. It has a generic e-paper display, a straightforward user interface, a QWERTY keyboard and the Android operating system. 

The price starts at $449. You can check out PCMag’s review of the Minimal Phone here.

Which physical phone keyboard should I get?

For now, the easiest way to get a physical keyboard on your phone is likely one of the Clicks accessories, since the keyboard case and power keyboard won’t require a full phone purchase. 

For most of these other devices, you’re entering a niche phone category, so support could be all over the place. You’ll want to check how many years of software and security updates these other phones are expected to receive. That way, you can have an idea about how many years of use you can safely get with these phones.

You’ll also want to consider how you want to use the device. If you’re looking for something that’s a step back from a more powerful yet constantly pinging device, the Clicks Communicator or the Minimal Phone might make a good secondary phone. The Unihertz Titan line and the Ikko Mind One may be a closer mimic of that BlackBerry experience.

I Asked Audiologists if My Earbuds Are Damaging My Ears

I spoke with ear health experts to learn more about the risks of wearing earbuds and which headphone style is best to prevent hearing loss.

I experienced hearing loss for the first time in early 2025 due to a case of eustachian tube dysfunction, which is when the tube connecting the middle ear to the back of the nose no longer functions properly. Even after I recovered, I was scared it would happen again. So as a wellness writer with 10-plus years of experience who understands the importance of being proactive with my health, I decided to do everything in my power to prevent hearing loss from affecting me again.

While researching ear health tips, I discovered that a common piece of technology, my earbuds, could have been contributing to my hearing issues. To find out if that’s actually the case, I spoke to ear health experts. This is what they had to say, and what they taught me about preserving my ear health.

Earbuds, ear health and hearing risks

Earbuds can pose a few risks, according to Dr. Ruth Reisman, a licensed audiologist and New York hearing aid dispenser. They can trap heat and moisture in the ear, increasing the risk of ear infections. With repeated use, earbuds can also push earwax deeper into the ear, leading to buildup or impaction. Plus, if your earbuds don’t fit correctly or you wear them for long periods, they can cause irritation or soreness in your ear canal. 

“Earbuds sit directly in the ear canal, which can increase several risks. The biggest concern is noise-induced hearing loss if volume is too high or listening time is too long,” said Reisman. “I have witnessed all of these problems in the course of my 15 years as an audiologist.”

When you listen to content at high volume, particularly for an extended period, Dan Troast, an audiologist at HearUSA, explains that it can permanently damage the delicate hair cells in your inner ear. Earbud use combined with high volume can cause:

  • Noise-induced hearing loss
  • Tinnitus (ringing, buzzing or hissing in the ears)
  • Sound sensitivity over time

Misusing earbuds is also common. If they don’t have noise cancellation, you might repeatedly turn up the volume to avoid hearing background noise, which can put you in an unsafe listening range fast. However, even listening at a moderate volume can become a problem if you do so for hours each day. 

“Early signs of overexposure include temporary muffled hearing or ringing after listening sessions — both are warning signals from the auditory system,” Troast said. Even if you periodically experience temporary ringing in your ears, it can ultimately increase your risk of developing chronic tinnitus. 

Earbuds and radiation

In my search for ear health tips, I came across several articles discussing whether wireless Bluetooth earbuds can cause harm through radiation. I asked Reisman if this is true. 

“Current scientific evidence doesn’t show that the energy from Bluetooth earbuds causes harm,” she said. “These devices emit far less radiation than cell phones and remain well below established safety limits. From an audiology standpoint, sound exposure is a far greater risk than radiation.”

The 60/60 rule you’ll want to follow if you wear earbuds 

Both Reisman and Troast recommend the “60/60 rule” to people who wear earbuds. The 60/60 rule means you listen at no more than 60% of the maximum volume for no more than 60 minutes at a time. 

“Daily use is fine if the volume stays safe and ears are given time to rest,” Reisman advises. “I usually tell patients to take a 15- to 20-minute break for every hour of use.”

If you haven’t already, Troast recommends checking whether your devices have built-in hearing health settings that automatically monitor volume exposure. For instance, on your iPhone, Apple Watch or iPad, you can set up headphone notifications to alert you to lower the volume when you’ve reached the seven-day audio exposure limit (such as 80 decibels for 40 hours over seven days). Or, you can activate the Reduce Loud Audio feature to have your headphone volume automatically lowered once it exceeds your set decibel level.

Safer types of headphones for your ears

Over-the-ear headphones are generally safer, according to Reisman, because they sit outside the ear canal and don’t concentrate sound as directly on the eardrum. Since they aren’t in the ear canal like earbuds, they’re also less likely to cause irritation or earwax buildup. 

“Over-the-ear headphones can be safer — if they allow for lower listening volumes,” said Troast. “Even better are noise-canceling headphones, which reduce background noise, so listeners don’t feel the need to crank up the volume.” Just make sure you’re still aware of your surroundings, especially if you’re outdoors near traffic. 

Open earbuds could also be a safer option. They use bone-conduction technology, which transmits sound through the earbones and the skull rather than directly to the eardrum. «Several headphone companies claim open earbuds are better for your hearing health and are more hygienic,» said David Carnoy, CNET’s resident headphone expert. 

Since open earbuds don’t sit inside or cover the ear:

  • Warmth and moisture, like sweat, won’t build up, which can cause ear infections. 
  • Debris, such as dust, won’t transfer from the earbuds into the ear. 
  • They won’t push earwax deeper in your ear, which can lead to impaction. 
  • Don’t rub or press on the ear canal, reducing discomfort or irritation.

However, if you listen to content at high volumes, no headphone style is completely safe. What matters most for your ear and hearing health is total sound exposure over time, so make sure you’re monitoring your volume level and giving your ears breaks. 

Expert earbud tips

If earbuds are your preferred headphone type for listening to your favorite music, shows and podcasts, Troast offers the following tips from an audiology perspective:

  • Use built-in volume limit settings on smartphones.
  • Choose noise-canceling earbuds or headphones to avoid increasing volume in loud environments.
  • Take regular listening breaks.
  • Avoid sleeping in earbuds.
  • Get a baseline hearing test, especially if you use earbuds daily.

If you’re already experiencing tinnitus, it’s especially important that you manage your volume level to prevent it from worsening. 

Carnoy adds that there have also been instances of people being allergic to the materials used for earbud tips. If you have a known allergy, make sure your earbuds don’t use that material, or replace the tips. If you do have an allergic reaction, stop using the earbud tips until you can find a substitute. 

Lastly, Reisman advises keeping your earbuds clean, avoiding sharing them and ensuring they fit properly. Most earbuds come with tips in different sizes, so you can find the right fit for your ear size.

When to see an audiologist or doctor

If you experience ringing in the ears, muffled hearing, ear pain or frequent infections, Reisman recommends you consider an evaluation with an audiologist. 

You’ll also want to pay attention to early warning signs of inner ear damage from noise exposure, such as ringing in the ears, difficulty hearing or needing to turn up the volume over time.

If you’re already experiencing hearing loss, Troast said that addressing it with hearing aids can provide relief. Tinnitus, on the other hand, can be treated with evidence-based approaches such as sound therapy or specific counseling strategies. 

“Hearing damage is gradual and cumulative,” Reisman said, “but it’s also largely preventable with smart and healthy listening habits.” And that includes using your headphones — or, in my case, earbuds — responsibly.
