Date and Time
Saturday April 2nd from 13:30 through 17:30 UTC
No downtime is expected.
Reasons for the Change
Mailsac is changing DNS providers to Cloudflare to provide a more resilient SaaS offering.
No customer changes are required. If you implemented IP based ACLs at the VLAN or border firewall, it is possible these rules may need to be updated. Cloudflare publishes a list of their IP addresses.
Saturday April 2nd 14:33 UTC
DNS has been switched over to use Cloudflare. All validation tests have been completed. We will continue to monitor for issues.
