Fibre aswell, 25/25Mbit cap atm, no download/upload limits. Rumors are it will be upped to 100/50 mbit within 2009, at the same price. But the ISP has yet to confirm anything.

35-40ms latency ingame.

[technical stuff]
More importantly, my ISP peers directly with Telia (and ofc a bunch of others), but since the wow-servers are served on Telia backbones in France, I get very few hops. I believe I have been dc'ed from wow less than 10 times since launch. Including server breakdowns, Draenor-EU had some serious issues at one time, where people was kicked off constantly. After they did some hardware upgrades and Draenor was included, those problems vanished and it has been a very stable realm since.
