YouTube is experiencing a major outage. Users across the world started to notice that the video service’s sites and mobile apps were down around 9:20PM ET, and everything remains inaccessible more than an hour later. YouTube TV and YouTube Music are also affected by the service disruption. YouTube has acknowledged the outage in a tweet. “We’re working on resolving this and will let you know once fixed,” the Team YouTube account says. “We apologize for any inconvenience this may cause and will keep you updated.” As of 10.35PM ET, the account is still replying to reports of the outage saying that the team is working on the problem. As with all Google-operated services, serious downtime for YouTube is pretty rare. YouTube TV did suffer service interruption at an inopportune time during this summer’s World Cup, however, and channel pages went down for a while in April.
