Please be informed that on February 7th, 2026, the Contentstack team will carry out a planned Redis cache upgrade to improve security and reliability.
Start: February 7th, 2026, 04:30 UTC End: February 7th, 2026, 08:30 UTC Duration: 4 hours Downtime: Brief (a few seconds to up to one minute)
Impact: During specific phases of the upgrade, users in the Azure NA region may experience brief, intermittent HTTP 401 (Unauthorized) responses within the Contentstack UI and Content Management APIs; these interruptions are expected to last only seconds to a minute, and while they will resolve automatically, users are advised to retry any impacted API requests or refresh the interface. Content Delivery services remain unaffected, and no further manual intervention is required.
If you experience any issues that persist beyond the migration window, please contact the Contentstack Support team.
