It's back.

I know because this chat room finally loaded. :V

The sites.

I don't know if they were entirely offline, but they were sooo slow... maybe the load balancers were hammering a single machine into submission.

SO/SE is like fire brigade nowadays, always waiting for an other fire to break out, trained to be always on foot for the rescue.

they must pissed off a lot of hackers, always a DDoS attack every couple of days
