mail delivery delay last night Nov 3rd

Message

Summary: We have had some complaints about mail delivery last night that it was delayed. We have found that the cause of this is similar to an issue we've found on other machines with 10GigE interfaces that are very new. There is a new driver that we will apply to all machines involved and that will prevent the issue from occurring again.

This affected inbound e-mail into our spam scanning server that sits in the Cloud. No e-mail was lost during this window. It was resolved around 00:00 last night.
