DICE says it's working around the clock to beat an ongoing denial-of-service attack against its Battlefield 3 servers.
If your recent attempts to play some Battlefield 3 have been thwarted by a message saying you've been disconnected from EA online, the odds are good that you're just one of many victims of a distributed denial-of-service attack that's been hammering the BF3 servers since at least the wee hours of May 8. "The current Battlefield 3 outages are a result of activity that appears to be aimed at overwhelming our back-end infrastructure," EA Community Manager Agent X explained on the Battlefield forums. "We are working on a variety of solutions to address this problem and are focused on resolution as quickly as possible."
Unfortunate, that effort doesn't appear to be going terribly well. "Despite our security measures, we have been working around the clock to mitigate the impact of an ongoing denial-of-service attack on our Battlefield 3 game infrastructure over the last several days," Agent X wrote in a follow-up nearly 20 hours later. "While the motives are unclear, the focus of the attack has been interference with network communications preventing access to multiplayer gameplay."
The good news is that no user data has been compromised; the bad news is that despite updates to Battlefield infrastructure servers, there appears to be no sign of the attack abating, as messages complaining about the inability to connect to the game continue to appear on the forum. DICE hasn't posted an update on the situation since last night, but did say in a tweet about an hour ago that it was continuing to look into the problem.
