12/23/14: Barracuda Email Security Service is currently experiencing delays with inbound email. This is affecting any Diligex customer who subscribe to Barracuda’s SPAM filtering services. We are working with Barracuda on the issue and hope to have an update soon.
UPDATE - 9:30AM: We have temporarily re-routed mail for all Diligex affected customers. Mail is now being delivered directly to customers' on-premise mail systems. There will be an increase in SPAM delivery during the temporary re-route. Any mail sent to affected customers early this morning, may stil be held by Barracuda and not be delivered until they resolve the problem within their network.
UPDATE - 2:30PM: Barracuda is still working on the issue. We apologize for the increase in SPAM during their outage.
UPDATE - 4:50PM: Barracuda is beginning to restore service. We hope to have mail routed back to their filtering service within the next few hours.
UPDATE - 9:30AM 12/24/14: Barracuda has fully restored service and Diligex has routed all affected customer mail flow back through Barracuda's filter.
Here is the post mortem from Barracuda:
