グローバルなCloudflareの障害がChatGPT、X、世界中の主要サイトを麻痺させる

A major Cloudflare outage today made many popular websites hard to use or unreachable. Websites that depend on Cloudflare’s services suddenly started showing errors or stopped loading properly. This affected social media, design tools, chat services, online games, and telecom portals.

Cloudflareの障害がX、ChatGPT、Canvaなどの主要ウェブサイトを妨害

何が問題だったのか？

Cloudflare was hit by the failure of an internal service, which caused the initial problem that could only be seen on their support portal.

Their content delivery and security checks were the next services hit when the problem escalated quickly. People who tried to open websites got a message like “ Please unblock challenges.cloudflare.com to proceed “.

The message is an indication that the site is under Cloudflare protection, but the verification of the protection is not functioning; therefore, users are blocked even if the site itself is okay.

Cloudflare offers DNS, CDN, and security to many companies, so a single point of failure can create the illusion that many different websites are down simultaneously when in fact it is only one.

誰が影響を受けたのか？

Among the services that had difficulties are X (Twitter), OpenAI’s ChatGPT, Canva, Spotify, Shopify, Discord, League of Legends, Garmin, and big companies like Claude and Verizon, T-Mobile, and AT&T.

In a lot of instances, the websites were not entirely offline, but users could not load feeds, use tools, or sign in.

Cloudflareのコメントは？

Cloudflare admitted the issues on their status page by saying that they saw “ widespread 500 errors, Cloudflare Dashboard and API also failing. “

They later posted that some of the services were coming back online, but they would continue to experience error rates higher than usual until the fix was completed.

これは何を意味するのか？

This Cloudflare outage shows how much of the web depends on a few big providers. The problem of one among them quickly spreads the impact to other providers.

Cloudflare customers may be thinking about the possibility of this kind of risk and preparing for it in the future.

Overall, the situation is gradually improving, but some errors should still be expected. If you keep experiencing difficulties, wait for a while and then try again or have a look at the official status pages. Cloudflare is committed to bringing the service back to full capacity as soon as possible.
