Updated: Online video fans might be wondering if the world has come to an end — after all, YouTube isn’t working this morning. When you try and check out YouTube.com, you get the “service not available” message. The videos embedded in other web sites are working without a problem. We will update the post as we get more information.

Update: YouTube has returned after more than 90 minutes of downtime. We’re still looking into what caused the outage this morning.

Update #2: YouTube issued the following statement regarding the downtime this morning:

“YouTube is up again following a technical issue which has now been resolved. We know how important YouTube is for people and apologize for any inconvenience the downtime may have caused.”
