We need to perform memory upgrades to two back-end mail servers, and would like to reserve the following maintenance windows for this work:

  • Saturday 26th March – 11pm-2am
  • Sunday 27th March – 11pm-2am

Hopefully we will be able to complete all the work in the first window. All being well, each server will suffer a downtime of approx 30 mins, during which time users with mailboxes on that particular server will not be able to access their email. After the work, the servers will actually run slower for a day, or two, while they refill their caches with frequently used data. Hopefully the timing of this work is such that this will go unnoticed due to the lower than normal loading anyway. We will send an update as and when the work is completed.
