Sony’s PlayStation Network was down for hours on Tuesday, frustrating gamers around the world who complained about being unable to log in to their accounts.

PSN said on its website that “some services are experiencing issues” and that players “may have difficulty” logging in, creating accounts, starting games or accessing video content.

“We are working to resolve the issue as quickly as possible,” it said. Sony did not immediately respond to a request for comment.

Data from Downdetector, an outage tracker, showed that reports first spiked late Monday and continued into early Tuesday, with thousands of reports filed hours after the problem first emerged.

It lasted about eight hours and affected virtually every service that required a PSN login.

It also came shortly after a recent update caused large ads to appear on players’ home screens – a bug that an official PlayStation X account said was due to a bug that was fixed on Monday.

The outage was mostly resolved in the U.S. and Canada by morning, and the PSN website said early Tuesday: “All services are operational.”
