I would spend the time that I would have used to be on here to track down the thing responsible for this horrible thing.
If it was a sentient being, I would make sure it suffered horribly.
And then I would bury it in its own entrails while I figured out how to bring the internet back.
But if I was so unlucky that the cause was not a sentient being...well, I'd probably go nuts.
Or go play some single player games.
