The problems appeared to be the result of problems with Cloudflare, an Internet infrastructure provider that feeds much of the Web. Many websites rely on the company’s tools to actually deliver their information and media to users, which means that problems with Cloudflare quickly hit other, obviously irrelevant, websites. People who visited these sites saw error messages instead of regular pages. “Eyes trying to reach Cloudflare sites in affected areas will see 500 errors,” the company said on its website. Immediately after the announcement of the problem, Cloudflare said that it had found the source of the problem and was implementing a fix. He then said that the repair was in place and that he “watched” for any further problems. Shortly after 9 p.m. UK time, said the incident was considered “resolved” and that the problems should be resolved. He did not provide any information on how the problems arose or what he had fixed.
