WotLK Latency has increasead

Hello, Warmane. I'm playing on the Blackrock realm and since Friday (the day when you changed market place) I have my latency increased form usual 36-44 ms to 72-200 with huge lagspikes sometimes? I tracert and pined logon.warmane.com in CMD tool and it looks the sam as before: no packet loss, e t. c.. At first I thought its my provider issue since at fridays evening I didn't have that much connection speed, but today at 8:00 am speed was good and latency is still 70+. If it says smthing, on Icecrown or other realm latency is 50+.

Idk what to do to make a picture of the problem atleast. Any help would be nice.
