A Cloudflare outage caused the \u201cInternal Server Error\u201d and \u201cError code 500\u201d problems"},"content":{"rendered":"<p class=\"wp-block-paragraph\">Around noon on 18 November 2025, errors such as \u201cInternal Server Error\u201d, \u201cError code 500\u201d and \u201cCloudflare Error\u201d messages appeared en masse. Many visitors saw blank pages, error codes or websites that wouldn't load, and the question arose: what was behind it?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The problem didn't come from the websites, the hosting providers or the browsers. The error was caused by a provider called Cloudflare, which handles the traffic of millions of websites worldwide.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Outlets such as AndroidAuthority, <a href=\"https:\/\/www.independent.co.uk\/tech\/cloudflare-down-twitter-not-working-outage-b2867367.html\" data-type=\"link\" data-id=\"https:\/\/www.independent.co.uk\/tech\/cloudflare-down-twitter-not-working-outage-b2867367.html\">The Independent<\/a>, <a href=\"https:\/\/www.windowscentral.com\/software-apps\/cloudflare-is-down-causing-outages-at-x-openai-and-even-taking-some-multiplayer-games-offline\" data-type=\"link\" data-id=\"https:\/\/www.windowscentral.com\/software-apps\/cloudflare-is-down-causing-outages-at-x-openai-and-even-taking-some-multiplayer-games-offline\">WindowsCentral<\/a> or the <a href=\"https:\/\/www.nytimes.com\/2025\/11\/18\/business\/cloudflare-down-challenges-error.html\" data-type=\"link\" data-id=\"https:\/\/www.nytimes.com\/2025\/11\/18\/business\/cloudflare-down-challenges-error.html\">New York Times<\/a> also reported that <a href=\"https:\/\/www.cloudflarestatus.com\/\" data-type=\"link\" data-id=\"https:\/\/www.cloudflarestatus.com\/\">Cloudflare's service<\/a> collapsed in several regions at once. The affected areas included Budapest, where the system showed \u201cCloudflare: Error\u201d while the browser and the website's server (\u201cHost: Working\u201d) were working fine.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What do \u201cInternal Server Error\u201d and \u201cError code 500\u201d mean in the case of Cloudflare?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Normally these errors would point to the website's server, but this time something else happened.<br>Cloudflare's own error page also showed:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>You \/ Browser: Working<\/li>\n\n\n\n<li>Budapest \/ Cloudflare: Error<\/li>\n\n\n\n<li>Host: Working<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This clearly means that the connection between the browser and the website's server broke in the Cloudflare layer.<br>In other words, the website itself wasn't faulty; Cloudflare simply couldn't serve the request.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That's why these errors, typical of common search terms, could appear:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>\u201cInternal server error Cloudflare\u201d<\/li>\n\n\n\n<li>\u201cError 500 Cloudflare\u201d<\/li>\n\n\n\n<li>\u201cError code 500\u201d<\/li>\n\n\n\n<li>\u201cCloudflare down\u201d<\/li>\n\n\n\n<li>\u201cCloudflare Budapest error\u201d<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">What caused the Cloudflare outage?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Cloudflare hasn't yet published a detailed technical explanation, but several sources have reached a similar conclusion:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>an internal infrastructure fault,<\/li>\n\n\n\n<li>possibly a faulty update,<\/li>\n\n\n\n<li>a routing or network disruption,<\/li>\n\n\n\n<li>or a planned maintenance may also have been behind it.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">It's important to stress that, based on the information available, <strong>it was not a hacker attack<\/strong>, not a data breach and not a security incident.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why did it affect so many websites?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Cloudflare is one of the world's largest traffic distribution and security systems. Millions of websites use it for speed, protection or DNS services. If an error occurs in a region, users may see entire pages with an \u201cInternal Server Error\u201d or \u201cError code 500\u201d message, even if the website's server is actually working perfectly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That's how completely different sites, news sites, webshops and services, could all \u201cgo down\u201d at the same time.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What can users do in a case like this?<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Wait until Cloudflare fixes the problem.<\/li>\n\n\n\n<li>It's worth reloading the page every few minutes.<\/li>\n\n\n\n<li>If you use a VPN, switching to another country may make the site work, because the problem depended on the region.<\/li>\n\n\n\n<li>You can check the problem by searching for terms such as \u201cCloudflare down\u201d or \u201cCloudflare status\u201d, or on Downdetector.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Website owners have nothing to do in this case: as soon as Cloudflare fixes the error, everything recovers automatically.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Summary<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Today's outages were caused by a large-scale Cloudflare failure. The \u201c500 Internal Server Error\u201d, \u201cError code 500\u201d and \u201cCloudflare Error\u201d messages don't actually indicate a fault with the website, but a central infrastructure problem.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There's no reason to worry: there was no hacker attack, no data was damaged, and the websites didn't break. Once the fault was fixed, all services came back or are gradually coming back.<\/p>","protected":false},"excerpt":{"rendered":"<p>2025. november 18-\u00e1n d\u00e9l k\u00f6r\u00fcl t\u00f6megesen jelentek meg olyan hib\u00e1k, mint az \u201eInternal Server Error\u201d, \u201eError code 500\u201d \u00e9s \u201eCloudflare Error\u201d \u00fczenetek.
