Hello,
The hosting company for the datacentre we have the servers in has informed us that there is essential maintenance work happening on Sunday 9th July from 10:00am for roughly 2 hours. They will be moving equipment and replacing some core network infrastructure and there will be a total outage during this time. They expect to be finished before midday assuming no unforeseen problems and the scheduled maintenance window is from 10:00am to 12:00 noon.
Email should be queued by the sending server during this outage period and will start arriving once the servers are up again. DNS lookups should be covered by the secondary server which is located elsewhere and will be still running. All web and server access will not be available during this period.
Regards,
Technical Support
