Grid Email Performance

We are currently working with our datacenter to investigate an system-wide email outage with our Grid email services.  Both GRID1 and GRID2 servers are offline and unreachable by email client and webmail.  Our datacenter is aware of the issue and is currently investigating the issue.  Check back here for updates.
Update 11am EST:
Incoming mail services are now back online however there are still some issues with volume where the server has too many threads.  This should get better through the morning as mail deliveries get caught up.
Update: 1pm EST
Incoming mail may be delayed as the queues are being processed for mail that came in while mail was offline.  Outgoing mail is also delayed because the server only accepts so many connections at a time.  This congestion should ease up as the day goes on.
Update: 2pm EST
All services should be back to normal at this time.  We apologize for the inconvenience.
