Bumping this, since I am now also affected. My ping from here in Germany was always steady in the 140-150 region which was (just) playable, now it's up to 200 and beyond with huge spikes (up to the 8000s) inbetween.
Running a trace the problem seems to be rooted at the same company Luxx mentioned: Internap (or pnap.net).
I'm no expert so I don't if this is general routing issue or something PGI can somehow address, I just know the game is unfortunately not enjoyable now, to a deegree where I just stop playing to not nerd rage all over the place.
Edit: Running a ping to www.mwomercs.com gives me all timeouts aswell. I have also send an email with all the info I had to the support.
