Our outgoing email service, smtp.aa.net.uk, is made up of multiple servers for resilience. One of these servers had a disk system failure over the weekend and has been taken out of service for repair. Before the server was removed from the pool it would have been reporting errors to customers trying to send email and not accepting connections.
At the moment we are running on a single server whilst the faulty one is repaired. We don't expect this to be a problem. Customers are able to send email OK.Email that was on the server before it died has been recovered and will be relayed on this morning. -This may mean a small number of emails will be delayed.
Queued mail on the faulty server was restored on Monday evening.
