Several major websites, including British government websites, The New York Times, CNN, The Financial Times and The Guardian, were inaccessible to many users on Tuesday morning.
According to Downdetector.com, which monitors internet disruptions, websites including Etsy, Hulu, PayPal, Reddit, Twitch, and Twitter also reported issues.
Many of the affected locations appear to have been restored in less than an hour.
The outage is connected to Fastly, a cloud computing service provider used by many companies to improve the speed and reliability of their websites. Quick then indicated on its website that the problem had been identified and a fix was being worked on.
Works fast on technology known as a content delivery network, which is a highly distributed network of servers used to reduce the distance between servers and users and speed up website loading.
This technology is said to improve reliability because it distributes the delivery of a website to multiple locations, rather than depending on a central data center. Fastly did not immediately respond to a request for comment on Tuesday.
Massive network outages are less common today than in years past, when Google and other big tech companies developed interconnected data centers to improve performance, but have there were some incidents happened last year.
In December, Google services including Calendar, Gmail, Hangouts, Maps, Meet and YouTube crashed for about an hour. The company attributed the problem to “the authentication system stopped working.” And in January, Slack, the popular workplace messaging platform used by millions of people worldwide, experienced a major disruption that prevented users from sending messages, loading channels, making calls, etc. call or log in to the service.
