Game periodically lagging for 2-5 seconds at a time

I seem to be getting big amounts of packet loss periodically, basically I will be playing for 10-20 seconds then it will completely lose connection for about 2-5 seconds and then catch up, this has been repeating since about 12 server time on Thursday and all through raid without stop, and seems to be ongoing.

Connecting to the server Barthilas from NZ.
