Microsoft Azure Outage in US West Impacting Multiple Kaseya Products

Incident Report for Kaseya Inc

Postmortem

Summary:

Between 2026-07-23 14:44 UTC and 2026-07-23 19:41 UTC, KaseyaOne customers were unable to access the KaseyaOne Portal, and authentication into integrated applications that relied on KaseyaOne SSO was also impacted.

Root Cause:

A network connectivity issue affecting the Microsoft Azure West US region caused service disruption for infrastructure supporting KaseyaOne. This resulted in loss of portal accessibility and SSO functionality until Microsoft restored regional connectivity.

Preventative Measures:

To reduce the likelihood and impact of similar incidents in the future, we are making Enhancements to Infrastructure Resiliency. Specifically:

Implementing a multi-region deployment architecture with designated primary and disaster recovery regions. This enhancement will reduce reliance on a single Azure region and improve service availability during regional infrastructure failures.

As a note; To ensure business continuity, for Kaseya modules using Require Log In with KaseyaOne, users must authenticate using their KaseyaOne Unified Login credentials. Users added as exceptions can still log in using local module-specific credentials. Details are available in this Knowledge Base article: https://help.one.kaseya.com/help/Content/1_Configuration/enable-require-login-with-K1.htm

We recommend adding a small set of users to the override list to maintain access in the event of a future disruption or maintenance, helping ensure continuous business operations
