A major technical hitch at technology giant Cloudflare has knocked ChatGPT, Twitter, and a host of other websites offline.
Users of websites which rely on the company’s services for cybersecurity experienced difficulties accessing such websites from about 12 noon in Nigeria.
ChatGPT failed to load for hours in some parts of the country, with the system showing that the CloudFlare server in London is down.
It was the same story for X (formerly Twitter), which also experienced some delay in loading fully, and Duplichecker, which was completely inaccessible, among a host of others.
Cloudflare provides cybersecurity and networking services to hundreds of major websites.
The company spokesman said experts were probing a “spike in unusual internet traffic” shortly before the issues emerged.
The official said the spike in unusual traffic to one of the company’s services started at 11.20 am on Tuesday, November 18, 2025.
He explained that the development caused some traffic passing through the company’s network to experience errors.
The spokesperson said while most traffic for most services continued to flow without any problem, there were elevated errors across multiple Cloudflare services.
He said the cause of the spike in unusual traffic remains unknown, but efforts are ongoing to make sure all traffic is served without errors.
The Internet glitch comes just weeks after hiccups at Amazon’s internet infrastructure division, Amazon Web Services, knocked a host of websites offline in the largest crash in history.
