As a result of last night’s power outage, there were some mail delays (and some senders may have received 4-hour notices). Obviously mail has been queued up on the external (and some internal) systems, which caused a spike after the services have been restored. As of now there are still some delays, but things are getting better.
One of the spam appliances had an internal failure last night, which caused it to not be able to properly scan email and deliver it. As a result, there were about 54K messages queued up. It is currently going through the queue and delivering those messages.
