Brief Network Issues at California Datacenter for MAX Mail

9:00pm Pacific — Our monitoring detected brief network connectivity problems at the California data center, beginning at approximately 8:25pm Pacific.  The issues were caused by a DoS attack against one of our upstream providers and were mitigated within a few minutes.  During that time, some inbound messages directed to that data center may have been deferred, and the control panel was slow or nonresponsive.  We have been monitoring the network status and have not seen evidence of any ongoing issues since approximately 8:30pm Pacific time.
