Affected Components: Fitbit

Nov 2, 17:40:00 GMT+0
Identified - Google turned off the Fitbit Web API on 2 November 2026. Terra can no longer fetch data or connect new users through the Fitbit integration. Fitbit users can connect through the Google Health integration instead, which is fully available. Other integrations are unaffected. Migration guide: https://docs.tryterra.co/help-center/help-topics/data-api-sdk/account-config-environments-and-going-live/fitbit-to-google-migration.

Duration: 3 hours and 48 minutes

Affected Components: Event Delivery

Oct 28, 16:50:00 GMT+0
Resolved - This incident is resolved. Between 13:02 and 16:50 UTC, an issue on our side caused some webhooks to be sent with an invalid signature, so endpoints that verify signatures rejected them. This mainly affected webhooks for data requested through the API, such as historical data requests, and some deliveries were delayed as a result. Rejected webhooks are being retried automatically with a valid signature and should arrive over the next few hours. If you temporarily disabled signature verification, you can turn it back on. No other action is needed..

Oct 28, 13:02:00 GMT+0
Investigating - We are investigating webhook deliveries failing signature verification..

Affected Components: Event Delivery, REST endpoints

Sep 29, 15:30:00 GMT+0
Resolved - This incident is resolved. Between 15:03 and 15:19 UTC, a large share of data requests to the Terra API returned errors, and webhook deliveries were delayed. Webhooks queued during this period were delivered once service recovered, and data requests were slower than usual until 15:30 UTC. Some users connecting Apple Health during the incident may have needed to retry. If you notice gaps in data from this window, requesting that period again will return it. No action is needed..

Sep 29, 15:03:00 GMT+0
Investigating - We are investigating elevated errors on Terra API data requests and delayed webhook deliveries..

Duration: 3 hours

Affected Components: Polar

Jul 15, 14:27:36 GMT+0
Monitoring - Fitbit's API is responding normally again in our checks. We are now working through the large backlog of notifications that accumulated during the outage, so Fitbit data will catch up progressively over the next hours — newest data first for most users.

Jul 2, 00:00:00 GMT+0
Monitoring - Since July 2, Strava has begun requiring developers to maintain an active Strava subscription (Standard Tier, effective June 30). Applications without one receive an “Inactive” response from Strava and stop delivering new data. Existing data is unaffected. If your Strava data has stopped, ensure the Strava account that owns your application has an active subscription, then reactivate the app in Strava’s API settings. Strava’s full migration deadline is September 1..
