It's working for me. Did it just go back up?
I hope this wasn't Anonymous, and Steam too?! This is crazy. The YouTube app is working on my iPad, but not the site.
Could be some server warehouse restarted due to power failure and YouTube and certain Steam servers just happen to be adjacent.
The Steam Store is experiencing some heavy load right now. Please try again later.
Went to store.steampowered.comOh boy...
