We recently discovered while exploring that Youtube has got trouble while loading and returning with different errors in results. We hope the downtime is not due to some serious issue and see how long does it take to fix it.
UPDATE: The issue has been fixed
Youtube has also notified its twitter followers about the trouble and the engineers are working on it.
UPDATE: TNW has reported a reason that the one of the racks in NY has been lost.
Youtube has just reported via another tweet that the issue has been resolved and all videos should be back now.
