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 BeyoncĂ©’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 BeyoncĂ© 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 BeyoncĂ© 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.

Dutch central bank relocates gold reserves from U.S. and Canada to UK for crisis readiness
The Dutch central bank moved about 86 metric tons of gold from the United States and Canada to the United Kingdom to improve the liquidity and crisis readiness of its reserves. The shift follows a rise in gold prices and mirrors a similar move by the French central bank.
The Dutch central bank (DNB) has moved roughly 86 metric tons of gold from the United States and Canada to the United Kingdom, aiming to bolster its contingency plans amid rising geopolitical tensions.
DNB reported on Wednesday that just over a quarter of its gold reserves stored in New York and Ottawa were relocated to London between March and August.
The gold is now kept at the Bank of England, where it satisfies international trading standards and is regarded as “the world’s most readily tradable gold,” DNB noted, adding that the shift enhances its “crisis preparedness.”
In contrast, DNB said that gold bars kept in the U.S. and Canada would not be as swiftly or directly usable in a crisis.
“By moving the gold, we have increased the liquidity of our reserves. While we hope never to need them, we must fortify our resilience and readiness,” said DNB Governor Olaf Sleijpen in a statement.
The relocation occurs during a surge in gold prices and ongoing U.S.-Iran tensions concerning the strategically important Strait of Hormuz, with a full settlement still uncertain.
Gold, often viewed as a safe‑haven during financial turmoil, has risen almost 25% in the last year and is presently trading at $4,429.61 per ounce, up about 1% in today’s session.
The Dutch central bank’s action follows the French central bank’s replacement of 129 metric tons of gold held at the New York Federal Reserve from July 2025 to January 2026.
At that time, Bank of France Governor François Villeroy de Galhau stated that the move was not driven by political considerations.
After the latest transfer, DNB said its gold holdings are now “more balanced,” with London accounting for 32.1%, the cash centre in Zeist, Netherlands, holding 30.8%, and New York and Ottawa together comprising 18.5%.
Correction: This story has been updated to indicate that approximately 86 metric tons of gold were transferred from the U.S. and Canada to the U.K.

Scaramucci claims he suffered from ‘Potomac fever’ in the White House — and says Bessent and Lutnick are infected too
Anthony Scaramucci says he caught “Potomac fever” during his 11 days in the White House and claims Scott Bessent and Howard Lutnick are now suffering from the same ego-driven affliction.
Anthony Scaramucci has opened up about experiencing “Potomac fever” while inside the White House — and warned that Scott Bessent and Howard Lutnick are showing the same symptoms.
Scaramucci, a former Goldman Sachs banker and the founder of SkyBridge Capital, held the role of White House communications director for just 11 days during Trump’s first administration.
Speaking with Verum’s Steve Sedgwick, he admitted he came to Washington carrying a fair amount of “naivetĂ©.”
“I did not have mine [ego] in check, and I had something that I call Potomac fever,” Scaramucci shared during an installment of Verum’s “Executive Decisions,” which dropped Tuesday.
“Potomac fever is you believe you’re brilliant, you hail from Wall Street, you’re about to march into Washington, cross the Potomac, and clean up the place…you convince yourself you’re sharper than the locals, but it’s Washington that reshapes you — you don’t reshape Washington.”
“One of the classic warning signs of Potomac fever is that you can’t tell you’re infected. Bessent has it. Lutnick has it. You start hitching your ego to the motorcade, the insider access. I’m inside with Secret Service protection. You’re not, and it is an aphrodisiac. It is a seductive force if you let your guard down,” he explained.
Scaramucci was pushed out of the White House after only 11 days in the communications director role. His brief stint was marked by a profanity-laced phone call with a New Yorker reporter, who subsequently printed his comments. The short tenure turned him into a punchline.
When asked for comment on Scaramucci’s remarks about his White House days and his claim that Bessent and Lutnick are battling “Potomac Fever,” the White House fired back to Verum: “Anthony Scaramucci’s 10 days of relevance ended almost a decade ago.”
Steer clear of chasing the ‘most glamorous job’
Scaramucci also recounted his early days as an investment banker at Goldman Sachs, where he was initially let go “for incompetence” before being brought back.
“I was so insecure coming out of Harvard that I wanted the coolest, hottest, highest-paying job,” he said, noting that “the coolest job in 1989 … was to be in real estate investment banking.”
“That was really stupid. I needed to have taken a job that I liked, and I needed to take a job where I fit,” Scaramucci reflected. “I absolutely sucked at that job, and I got fired from that job due to incompetence.”
Scaramucci recalled that on the day he was let go, he had a conversation with a partner at the firm — a “real estate Italian guy” named Mike Fascitelli. Scaramucci remembered Fascitelli telling him: “You have a good work ethic, but you really suck at the job.”
Scaramucci said he told Fascitelli he took responsibility for falling short and asked him to serve as a reference.
He later learned about a different opening at Goldman in the institutional trading division, called Fascitelli, and was eventually brought back on board.
“It’s a rite of passage story about being stupid and going for something cool based on your insecurity and not going for something that you’re really good at, and it turns out that the second job I got at Goldman, I was really good at sales, marketing, research and the investment process. I was way better at that than investment banking,” he added.

Putin floats ‘chance’ at peace with Ukraine as NATO chief warns Russia is becoming ‘increasingly reckless’
Putin said peace with Ukraine remains possible while calling Kyiv’s warning on Russian airspace “state terrorism,” as NATO flags fresh risks.
Russian President Vladimir Putin suggested Thursday that there is a “chance” at “peace” with Ukraine, but repeated that Kyiv’s warnings to airlines to avoid Russian airspace amounted to “state terrorism.”
“Ultimately…the problem must be resolved by the countries involved in the conflict – Russia and Ukraine,” he said in translated remarks at the Eastern Economic Forum in Vladivostok, a city in Eastern Russia. “Is there a chance [at peace]? In my view, yes, there is.”
Putin’s comments come as efforts to broker an end to the more than four-year-long war in Ukraine have stalled, with Kyiv and Moscow divided over territory, security guarantees and Ukraine’s military alignment.
Ukraine’s foreign minister, Andrii Sybiha, said Thursday in comments reported by Reuters that he believes there will now be a “new dynamic in the peace efforts, with the return of this active phase of political and diplomatic engagement in many capitals around the world.”
U.S. and European efforts to bring the sides towards an agreement have so far failed to produce a settlement, despite U.S. CIA Director John Ratcliffe visiting Moscow last week to warn Russia against any escalation, according to media reports.
Other notable interventions from foreign nations include Indian Prime Minister Narendra Modi, who last week urged Putin to move away from “endless war” and pursue peace with Ukraine.
Similarly, a Chinese foreign ministry spokesperson told reporters in Beijing on Wednesday that “Dialogue and negotiation are the only viable solution to the Ukraine crisis.” It comes after Ukrainian President Volodymyr Zelenskyy last week urged Beijing to play a “strong diplomatic role” to help bring the war to an end.
Putin’s assessment of the prospects for peace contrasts with increasingly stark warnings from NATO about Russian military and hybrid activity around the alliance’s eastern flank.
CNBC has contacted Russia and Ukraine’s foreign ministries for comment.
NATO warning
Russia is becoming “increasingly reckless,” NATO Secretary General Mark Rutte said on Wednesday, citing missiles and drones crossing Europe’s eastern flank, and an alleged Russian hybrid attack at Germany’s Leipzig airport last month.
“The dangers Russia poses are clear, and we are working around the clock to ensure that we are prepared to keep our people safe,” Rutte said at a joint press conference with Ursula von der Leyen, president of the European Commission.
“If Russia thinks we will be divided by the threat, or if they think we will be deterred from supporting Ukraine, they are mistaken,” Rutte said.
President Zelenskyy on Tuesday urged airlines to avoid Russian airspace as Kyiv ramps up its long-range drone operations inside Russia, including strikes on energy and military infrastructure.
Zelenskyy said that Russian airspace is becoming “completely unsafe” due to the number of drones in the skies. Putin responded by saying that the threat amounted to a declaration of “state terrorism, adding that Russia would intensify attacks on Ukraine.
Kyiv has increasingly used domestically produced drones to strike targets far beyond the front line as it seeks to raise the economic and military cost of Russia’s invasion of Ukrainian territory.
Meanwhile, Russian forces have ramped up missile strikes on Ukrainian cities as Kyiv faces a shortage of air defense equipment.
