Issues authenticating with Azure DevOps in Appflow

Incident Report for Ionic Services

Postmortem

On January 6th, 2026, at 1:53 PM EST, Appflow's Azure DevOps integration stopped working. Customers using Azure DevOps as their git provider were unable to authenticate, link repositories, or run builds. The issue was caused by the expiration of our Azure DevOps OAuth client secret, which had been valid for 5 years since its creation in January 2021. The incident was reported on January 7th, 2026, at 12:27 PM EST, and initially resolved at 3:27 PM EST by rotating the secret and redeploying the authentication service. However, on January 8th, 2026, at 11:04 AM EST, we discovered that builds were still failing because a second service (appflow-apps) also had a copy of the expired secret. Full resolution was confirmed at 12:51 PM EST after updating the secret in both locations.
