You're right boox, it's most likely just a server issue... but ya never know... I mean, does someone really need a good reason to launch such an attack? And when I think about it, both sites could at times have content that might rub certain fringe groups the wrong way... and it seems it doesn't take much these days to do so really.
The strange thing is that I've recently noticed that both sites are down simultaneously... and for about the same amount of time... very weird. And I don't think they're both owned and operated by the same person(s), or that they reside on the same server(s).
Oh well, just an odd coincidence I guess.
