The network connection is fine.
In that case, please wait a few hours. There are currently no other reports about this issue. I also checked by playing the game for about 10 minutes and did not experience any problems.
This issue has already been going on for nearly two weeks now, it's just that not all servers are affected.
There is an active thread on the forums here, I'm trying to link to it but it gives me an error. It's titled "Servers are (almost) unplayable: lag + stuttering".
I believe this is the post in question.
It's actually this one:
