PostHog feature flag api errors impacting on accessim.org

Started 28 Oct 2025 20:06:07 (6 days ago), resolved 29 Oct 2025 14:15:56 (5 days ago)

Minor Incident

Resolved

AccessIM

PostHog feature flag api errors are making some features on accessim.org inaccessible. This includes features like math tools that only show up if the relevant feature flag is set to true. Since the app can't get the result of the feature flag, it defaults to false, thus hiding the feature. Engineering is monitoring PostHog status updates, and will update when we have more information.
