when such gaints can run into a problem, what makes you think they can't be shut down ?
LONG LIVE BTC, 100% UPTIME

This is just like a maintenance on big exchange so I think it will not ne shut down for good. But of course, bitcoin will live longer but it doesnt mean that we will not encounter any problem, i guess whats happening on facebook is normal since many companies wants to kill facebook but I know it will be back better.
