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.

Nintendo Switch 2: Every Reveal About the Console, New Games, Price, Release Date

The $450 console launches June 5, with Mario Kart World the highlight of its launch day game lineup.

The Nintendo Switch 2 console’s biggest reveal yet arrived Wednesday as part of the company’s latest Nintendo Direct event. This teed up a day of Switch 2 reveals that include its June 5 release date, a $450 price, its specs and its initial game lineup that extends from launch into 2026.

The console will be further buoyed by having Mario Kart World as a launch title, which will go on sale in either a $500 bundle with the Switch 2 or on its own for $80 — making the open-world racing game one of Nintendo’s most expensive yet. Other games announced, such as Donkey Kong Bananza, are being priced around $70, which matches the cost of 2023’s The Legend of Zelda: Tears of the Kingdom. That Zelda game and Breath of the Wild are among the original Switch titles that will get enhanced Nintendo Switch 2 Edition upgrades, a premium upgrade allowing players to get new features, modes and graphical enhancements that take advantage of the newer system’s capabilities.

Here are the top highlights from Nintendo’s console event, all of the games we’ve heard about so far (including new titles, Nintendo Switch 2 Editions and GameCube games coming to Nintendo Switch Online) and all of our coverage so far. You can also check out our Nintendo Switch 2 live blog for even more updates about the Switch 2 as we learn them.

Nintendo Switch 2 console

The Nintendo Switch 2’s specs saw a noticeable technical bump over the Switch. The Nintendo Switch 2 has a 7.9-inch, 1080p resolution LCD that supports a 120Hz refresh rate — matching what we now see on most Android phones. When the Switch 2 is docked, compatible games can run in 4K resolution. The new dock also includes a cooling fan.

The Switch 2 comes with 256GB of internal storage, and the new Switch 2 Game Cards will load games faster. For digital libraries, however, the Switch 2 will only work with microSD Express cards, which are different from the microSD cards that are compatible with the prior Nintendo Switch. Nintendo will have a Software Transfer feature available to help move games and data from the original Switch to the Switch 2.

The new Joy-Con for the controllers will support mouse controls, and a new C button will be part of a new GameChat communication feature that allows both voice and video chat. There’s also a Nintendo Switch 2 Camera, allowing players to see each other.

The Switch 2 also adds a second USB-C port to the top of the system, which Nintendo says can help connect its new camera accessory or charge the console when playing in tabletop mode. Nintendo also revealed a new Switch 2 Pro Controller with the C button and customizable GL and GR buttons on the back.

Following the presentation, Nintendo unveiled the system’s price of $450 in the US. It will also sell the Switch 2 bundled with a digital version of Mario Kart World for $500.

Mario Kart World

Mario Kart World removes its traditional boundaries and lets drivers roam freely across an entire world of race courses. The game will get its own Nintendo Direct later this month, where we’ll see additional details, but we already know it’ll include traditional races and a Free Roam mode, much like in the Forza Horizon series.

Getting the game bundled for an extra $50 on the cost of the Switch 2 might be the move if you are interested in the game, because Nintendo announced on its website that standalone copies of Mario Kart World will cost $80.

Joy-Con 2 C button and GameChat

Nintendo’s rolling out its new C button across several new Switch 2 controllers. The button will be used for the new GameChat communication features without a headset. The button will be used alongside a microphone on the console itself, which Nintendo says can be used whether it’s docked to a TV or in handheld mode.

In its teaser video, Nintendo promises the microphone will be able to cancel out loud background noises. GameChat will also work with a Nintendo Switch 2 Camera, allowing video chat and various camera-based game modes in supported titles. GameChat will be free at launch through March 31, 2026.

Nintendo Switch 2 Edition games upgrade titles

The Nintendo Switch 2 will play three types of games: original Switch games, Switch 2 games and Switch 2 Edition games that will receive substantial enhancements. For many of these Switch 2 Edition games, you’ll need to buy an upgrade pack if you own the original for Switch. Many of them will get more than just enhanced graphics in the upgrade; for example, Super Mario Party Jamboree will get new games that support the new Joy-Cons’ mouse controls, audio recognition and video camera gameplay options through the Switch 2 Camera.

Other Nintendo Switch games that are getting Switch 2 Edition options include The Legend of Zelda Breath of the Wild, The Legend of Zelda Tears of the Kingdom, Kirby and the Forgotten Land, Metroid Prime 4 Beyond and Pokemon Legends: Z-A. Enhancements vary: The Zelda games will start working with a companion phone app for maps and sending schematics to friends, while Kirby will get a new story that’s exclusive to the Switch 2 Edition. On the third-party side, Civilization 7 will get mouse controls.

Nintendo did not announce what upgrade packs will cost. However, some Switch games will get free updates that will improve performance or enhance features when playing them on the Switch 2. The Switch games getting these updates include:

Hyrule Warriors: Age of Imprisonment

Hyrule Warriors: Age of Imprisonment is a new game set in the world of Zelda that tells the story that leads into The Legend of Zelda: Tears of the Kingdom. This appears to be similar to how Hyrule Warriors: Age of Calamity told the story of a war that led to the events of Breath of the Wild. The teaser shows Zelda discovering that she’s arrived in the past of Hyrule, and the game will expand on how she gets involved in the corresponding Imprisonment War.

Nintendo Switch 2 games

Several other first- and third-party games were spotlighted during the Switch 2 Direct. These include Donkey Bananza, one of the first 3D platforming games featuring DK since 1999’s Donkey Kong 64. Kirby will also return to the racing genre in Kirby Air Riders, which comes more than 20 years after the GameCube racer Kirby’s Air Ride. DragXDrive will use mouse controls to control a futuristic wheelchair basketball game in which players will simulate push and pull motions to control their character.

An onslaught of Switch 2 third-party games were quickly shuffled through during the Direct, which I list below. An unnamed James Bond game is in development at Hitman studio IO Interactive, as is a darker title from Elden Ring creator FromSoftware called The Duskbloods, which will be exclusive to the Switch 2.
