Websites including X and Spotify have been hit by a major outage linked to Cloudflare.
Thousands of users reported issues with a host of different websites, including the film review site Letterboxd, which were impacted by technical issues at the internet network services business.
The DownDetector monitoring site, which was itself hit by the outage, showed a flurry of reported issues after 11am on Tuesday.
More than 10,000 DownDetector users reported issues related to Cloudflare.
A number of the websites affected, including X, came back online temporarily before suffering further problems.
Users saw a message on a number of the websites saying the issues were caused by an “internal server error on Cloudflare’s network”.
Cloudflare provides network and security services for many online businesses in order to help their websites and applications operate.
