That could be a local internet issue (your location), get WinMTR and check your connection on 68.142.64.210 (Istaria's server) low numbers are good and high are bad. Packet loss is also bad. Just checked my connection to the server and its 0% loss, 108 Avg (good). I go throw 17 servers to get to www.istaria.com. A guild mate from the UK has problems early morning UK time too.
