Advisory: Reflexion - Delayed delivery of outbound and inbound email

[Update] 7/31/2019 - 7:15AM EDT

As of 6:30 AM EDT, Reflexion services continue to process the backlog of email that was delayed as a result of the outage yesterday.

• No email was lost, and we expect all queued email to be delivered over the next few hours.

• Our infrastructure engineering teams continue to monitor and are actively working to resolve the issue and restore regular mail flow as quickly as possible.

• Reflexion Outbound mail is delivering without issue.

• Again, we sincerely apologize for the inconvenience this has caused and will provide an update once the queues return to normal or there is additional information to share.

7/31/19 - 2:30PM EDT - Update on Issues with Reflexion Email Security Service:

• As of 2:30 pm EDT, all inbound and outbound mail delivery through Reflexion is returning to normal, although some end users may periodically notice delays due to the high volume of emails we are currently processing. We expect that any delays will continue to improve as the queues are processed. We will continue to provide updates as the operation progresses back to a fully healthy state with no delays.
• Please know that all email that was queued in the last 24 hours has been safely processed and will be sent and received as the flow resumes - no emails were lost by the Reflexion operation as a result of this issue.
• We expect improvements throughout the day. The operations and development teams are diligently monitoring the service to ensure all Reflexion customer email is fully resumed. Note: This issue affected customers of the Reflexion service and did not impact any of our services in Sophos Central.
• While we are still finalizing the root cause of the problem, we have determined that during the initial incident the IO limits of our storage infrastructure was exceeded, due to a routine maintenance process that was executed incorrectly. We are continuing the investigation and will provide a thorough root cause analysis (RCA) once complete.
• We sincerely apologize for the inconvenience this has caused and will continue to provide updates during the day. Please continue to watch this KBA page.

Any info on queue sizes?  I'm still seeing delays on the couple of customers I have still using Reflexion.  Everyone else is bypassing it for now.  I'd like to set everyone back but I don't want that to do that until I know email is back to normal.
