The good news is that WAN speeds are back to normal here. Shaw found something that was misconfigured somewhere in their system and all is well again.
The bad news is that TPU may not be showing up in some users' Battlefield 1942 in-game server browsers. I've checked with a few players, and it shows up on some, but not all of their server lists.
If you can spare a few minutes, please check your in-game server browser and let me know if you see "Tanks 'n Planes Unlimited CO-OP". Don't forget to click the UPDATE button first. Thanks!
