Maintenance Notice: DNS Provider Change

Date and Time

Expected Downtime

No downtime is expected.

Reasons for the Change

Mailsac is changing DNS providers to Cloudflare to provide a more resilient SaaS offering.

Customer Changes

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.

Updates
