DNS Tool

Continuous DNS monitoring, health validation, and change alerting for your private and public Azure DNS zones

Generally available·snapshot 2026-11-15.1

Data residency and data protection

DNS Tool is hosted on Microsoft Azure in the EU, and customer data is stored and processed in the EU only, including AI processing by Mistral with zero data retention. Other data residency boundaries are not currently offered for DNS Tool.

On Pro and higher plans, AI assesses how critical a detected DNS change is, to help customers prioritise alerts. This is on by default and can be switched off by the customer.

Availability and continuity

DNS Tool has a 99.5% availability target, covering continuous DNS monitoring, health validation and change alerting.

Monthly availability targets. A plane is one part of the service measured on its own; each row has its own target.
Plane	Monthly target	Why
DNS monitoring, validation and change alerting	99.5%	Covers the service as a whole. During an outage, DNS changes and health issues are not detected or alerted on until the service recovers. Your DNS zones themselves are served by Azure DNS and are not affected.
