Ahh, so that explains why I haven't been paid my mining profits yet today. The mining site shows that the payment went out but it's not registered in my wallet yet. Is this sort of thing normal? I've seen delays a few times but this seems bigger than usual.
And isn't the price of btc up today too? I'd think this is the sort of issue that would drive the price down more.
A stress test was or is being performed today:
