Update: Respawn Entertainment has said it's ironed out these problems. "Our team has resolved the PC connectivity issues and you should now be able to connect to matchmaking servers," reads a tweet from the developer.
The original story is below.
EA's support site says that the PC version of Titanfall is experiencing "connection problems" which could affect your ability to play the game.
"Titanfall is currently experiencing connection problems," reads the support site following the game's launch in the US yesterday, "which means you may not be able to connect to online play, or even might get dropped from an online match you're currently playing."
"Rest assured that we're addressing this problem and will provide updates as soon as possible."
Xbox Live ran into a few problems of its own last night, although Microsoft later clarified that these issues weren't related to the Titanfall launch.
