Massive latency today

Been here for over a month seriously i think, and never had any problems like this before. my latency is currently over 1100ms, sometimes dropping to 700. i am in canada, so i usually get 140, which is great. but today i cant play, trying to do anything with that kind of latency is a death sentence. i've done everything on my end i can think of; wiped cache, rebooted everything, checked everything (only issues with network are with wow), and disabled all addons. think there was something else i tried too, but without success. on loderan, if that matters.

is there anything i can do? is this an issue being worked on?
