Server NC027 (the primary mail server) will be migrated to new hardware during our regular weekly maintenance window next weekend. This maintenance will start at 20:00 UTC on Saturday 9 December 2017, and should conclude within one to two hours. During this time the mail server will be offline. This means that all incoming mail to domains hosted on this server will be queued on the sending servers, and delivered to this server when it comes back online. It also means that you will not be able to send email during this period.
We will post an update here shortly before, at the start of and following the maintenance.
If you have any questions or concerns, please contact support to let us know. Thank-you.
