Streamed video issues?

I have a pretty new Ipad. So far there has been no issues but today all of a sudden streamed content from sites like Youtube and Youtoons.se started malfunctioning. The videos just won't play. Network connections are otherwise fine and the Safari browser has no problem reaching the sites or any other sites for that matter.

Youtube states an error occurred and "TV noise" instead of the video, Youtoons just shows a black box where the videos should be playing.

Any ideas?
