Over the past few days, it has been nigh-impossible to connect to servers in the PC iteration of Battlefield 4 thanks to an unnamed group attacking EA's Origin servers. Initially the publisher posted a statement to the main page of Battlelog stating that attacks were occurring and that the company was working to mitigate them, but as Kotaku reports, this message has since been removed. Despite this, one of the game's community representatives offers the following in the game's forums: "[W]e are being targeted by a DDOS, but working on fixing it asap. Im sorry somebody is ruining your and my day. Rest assured we are doing our best to mitigate the situation though."
The PlayStation 4 game saw even worse issues, with players reporting crashes, a total inability to connect to Battlefield 4's "Conquest" game type and periodically deleted save games. EA's immediate response involved adding a new server and issuing a sizable patch, but as I can personally attest, the crashes and deleted save files continue to be an issue for some players.
On Sunday, the publisher posted a message to its Help site pinning the blame on the PS4's recent 1.50 firmware update. Specifically, it claimed that "this update ... results in stability issues while playing games on the system," and that all games are affected, not just Battlefield 4. This message has since been retracted, and in its place you'll now find a simple, "The message on EA's Help site was posted in error."
