Access has been restored, and users should now be able to sign in normally.

The earlier ACE AVD logon issues were caused by a Microsoft authentication problem linked to a recent Windows security update and have now been resolved.

We are investigating an issue affecting the ACE AVD Pool where users may encounter a “Logon Failure” error message when attempting to sign in.

We will provide further updates as soon as possible, and apologise for any inconvenience caused.
