I applied new network settings to clients around the same time as the server move. It's a bit unfortunate that the changes happened at the same time as it makes it hard to untangle causes from anecdotal evidence. I found that turning of the smooth buffer and making the network connection fast results in much better ping compared to the previous hardcoded values (which correspond to reliable network and smooth buffer enabled). I have not noticed much latency variance, but it could be different for different people.
Go to Game under the lobby Settings menu and change Network Connection and Smooth Buffer. Try turning Smooth Buffer on.
It would be good to have the donations page updated. Licho doesn't seem to have gotten around to it.
