Youtube went down for a little more than an hour on Tuesday, October 16, a rare outage for the Google-owned company.

The video-streaming site, which has nearly 2 billion monthly active users, began suffering issues globally at around 9 p.m. ET on Tuesday.

During this time, the website and apps weren’t fully accessible. On desktop, for example, the site showed parts of the homepage together with a string of incomprehensible text and a statement saying its engineers are dealing with the issue.

About an hour after the problems began, YouTube posted a message on Twitter acknowledging the issue and apologizing to its users for the blackout:

“Thanks for your reports about YouTube, YouTube TV, and YouTube Music access issues. We’re working on resolving this and will let you know once fixed. We apologize for any inconvenience this may cause and will keep you updated.”
