Latency Has Rendered the Game Unplayable

Has anyone found a way around the latency issues? After all my years of playing GW2 it's never been this bad.

Immediately after logging in I get multiple pop-ups of the "Log in server" error, and then the game just inevitably loses connection; it either crashes to character select or the world "freezes" in perpetual motion forever. I gave up trying to pvp because I keep losing connection in the map and getting flagged as a deserter, and any PvE just leaves you dead. So... I'm going to have to shelve the game for a while until this gets addressed. Does anyone have any suggestions?
