I would have blamed it on the local service anyway.
The local service drops out way to often. Sometime there is days without any disconnects. And then there is hours with as many as 6 disconnects.
I have a screen shot from March 4 of a one hour graph.
Back to the topic though, I've not noticed anything strange after the first few hours of switching over the servers. There for a few hours I couldn't "Mark Forum Read". That was fixed after a little time.
