The fact that FB and all of its services were down at the same time can't really be a coincidence, can it? Is Facebook trying to delete incriminating evidence?

The fact that FB and all of its services were down at the same time can't really be a coincidence, can it? Is Facebook trying to delete incriminating evidence? It wouldn't surprise me one bit if they did that. I hope the prosecutors are smart enough to look for evidence of this, even though I'm sure FB's experts will try to leave as few traces as possible.
