Some users were unable to connect to the Streaming API at various times during the DDoS. This has been fixed for the majority of Streaming API clients. The connection count is now approaching yesterday's count.
If your Streaming API client is still receiving 409 redirects, connection timeouts, or any other issue that started today, please contact me with your account name and IP address, and I'll work to resolve the issue. -John Kalucki http://twitter.com/jkalucki Services, Twitter Inc.
