Maintenance Notice - UltraDNS NAT IP Migration - November 15th 2026Planned Maintenance

Schedule

November 15, 2026 5:30AM - 9:30AM UTC

Components

UltraDNS, UltraDNS2

Service

Secondary Zone Transfer

Description

During the maintenance, UltraDNS will move the NAT IP addresses used by the SZTS service, which runs zone transfers for secondary zones, from the old network to the new one. The current transfer IPs stay the same but moved to the new network. This release also adds support transfer over IPv6. The issue is temporary and limited to the maintenance window. The zones will refresh at its next SOA refresh. Customers may run a force zone transfer for affected secondary zones, if a update is needed immediately. DNS resolution is not affected. No changes are needed to be made by customers. The UltraDNS transfer IPs remain the same.

History (Last 7 days)

UltraDNS Traffic Services MaintenancePlanned Maintenance

Description

UltraDNS will move the Notifier service, which receives DNS NOTIFY messages for secondary zones, to a new network. The current IPv4 NOTIFY addresses stay the same and are moved to the new service one at a time. This release also adds support for NOTIFY over IPv6. During the window, NOTIFY messages sent to the UltraDNS NOTIFY IPv4 addresses may not be received for short periods while each address is moved. Updates to secondary zones may be delayed during those periods. Zone changes are still picked up through the regular SOA refresh. The IPv4 NOTIFY addresses customers use do not change, and no customer action is needed. No impact is expected on DNS resolution.
