This incident has been resolved and historical data is available again.

We are bringing our services down while we execute the process to return access to the historical data.

Services will be unavailable for 10-15 minutes while the process completes.

We rolled-out a fix and are currently monitoring the result.

Previously stored historical Indoor Air Quality data will be temporarily unavailable while we work to migrate that data into a unified data store.

Services are returning to operational status, however, we are continuing to rollout a fix for this incident to bring all services back online.
