Past Incidents

Scheduled maintenance SEPPmail Cloud DE instance: additional IP ranges from 2026-04-01 10:00 CEST to 2026-04-01 12:00 CEST
[Scheduled]

The extension setup of SEPPmail Cloud DE instance is about to go live. With added performance, geo redundancy and hoster redundancy we are ready for future growth. In early April traffic will start with a few selected NFR partner domains, before gradually going into production with all customers once the new IP addresses have warmed up sufficiently.
