Guild Wars 2

About 1 week ago I get ping troubles with gw2 servers. Usually before this my ping was about 30-40, now it`s always 100 min and smtimes jumps to 800-1000
This troubles only with gw2 (I think) cos ping command for google.com (for example) give me about 2ms delay, and ping guildwars2.com give me about 90ms delay.
What`s wrong and what can i do?
P.S. Sometimes after 3-5 relog i get my ping 40, but after i go for another map (PvP match) i again get ping 100
I`m playing from Russia, and some ppl get same troubles, but most dont have any problems. I also think that it can be my provider problems, so how i can check it and what i should do in this case?

you can download Ping Plotter (www.pingplotter.com) and run the test to a map ip (type /ip into chat in game, then type that into ping plotter) it can show you where the problem is.

you will run it and it will point to link.telia.net and that will somehow be your fault

same problem thats been ongoing for months and months
