Battle.net is currently being affected by a distributed denial of service (DDoS) attack. While this is ongoing, you may have trouble connecting to games or services on Battle.net, or encounter high latency or disconnects once you have connected.

We are taking measures to improve stability and connectivity as quickly as possible. Until the issue is resolved, we will post news every hour on our official support Twitter feed, @BlizzardCS. Please check there for the latest information.
