As part of our continued strive for security excellence, it is necessary from time to time to upgrade our core server software. During the month of September 2023, we are planning a number of short outages out of hours in order to upgrade our email server software. These upgrades will cause short delays for both inbound and outbound emails during out of hours, for periods lasting up to 1 hour.
Updates to our work affecting you will be posted below…
