4 days and k2 hasnt made any announcements about the issue.
so lets make some assumptions of our own as to why the servers are laggy.
-To reduce costs, they changed to dial up connection from high speed.
-A gm wasn't happy about the pay rate so he decided to delete some important files off the system.
-They tried to patch something without the help of mgame, and now require mgame to fix it for them.
-Someone tripped over a wire and they cant figure out why its lagging.
-They forgot to pay their ISP bills
thats all i can think of right now :P
