We are carrying out disruptive work on our webmail service: https://webmail.aa.net.uk/ We will carry the work out in the morning, and don't expect the disruption to be long. The window here is thirty minutes from 7:45, but it should only be a five to ten minute outage.
The work is still ongoing, so webmail should still be considered at risk, but the disruptive part of this work is complete and there should not be any further interruption.
This work is completed.
