Says servers may have problems.
Blizzard posted a warning these evening that their servers are experiencing a distributed denial of service attack, and that players may experience high latency. And if you don’t believe me, see below for the Tweet confirming the situation. If you don’t believe the tweet I’m afraid I can’t help you any further.
[#BNet] We are currently experiencing a DDoS attack, which may result in high latency and disconnections for some players. We are actively working to mitigate this issue.
