I've seen that some other people have had this issue on the Battlelog as of yesterday. Whenever I head to the battlelog and try to join a multiplayer server or jump into the campaign, the battlelog will infinitely say "joining server" (for multiplayer anyway). Origin says it is launching BF3, but then nothing happens. I checked task manager and the BF3.exe process appears, then vanishes, along with the EA Server process. I only know of a few other people who have had this problem, and only as of yesterday, so I don't know how many people can understand the issue.
