Email Defense is experiencing intermittent delays on incoming email. This is being investigated by our vendor. We will update this post when we have more information.

UPDATED 2:00 PM ET: The cause of the delays is a SYN flood DDoS attack on the email defense servers. Our vendor has taken steps to minimize this and mail is flowing better now but still not back to normal. They are continuing to work with their networking operations and upstream providers to minimize this.

UPDATED 2:15 PM ET: The delays have been minimized and mail is now flowing normally. We are waiting for an update from our vendor before calling this resolved.

UPDATED 7:35 PM ET: This issue has been resolved.
