I see I multiple posted during that DDOS attack (I'm guessing it was an attack, anyway).
I don't know about their server upgrade, but even if they're new, a DDOS attack can still overload servers, because it's an attack that overwhelms the servers' ability to answer all incoming requests because of the massive incoming volume.

I suspect you’re right.
