Because of an influx of new web clients we’ve had to upgrade our servers to a better suited setup.
Accounts and their contents will be mirrored from the old server to the new server, after which the DNS records will then be updated after every account has made it over successfully.
As of this moment there isn’t expected to be any downtime or loss of functionality since the accounts are being copied and not transferred.
UPDATE 9/1/18 10:45 am PST:
The migration has been completed successfully and all sites appear to be functioning properly. You may notice slightly slower loading the first time you visit your website after the migration due to web browser caches being updated, however this will have little effect on actual site performance.
