Update

The main part of the maintenance operations is done.

As expected, the database failover showed a brief increase of error rates that recovered after seconds.

We're cleaning up things that should have no customer-facing impact now and keep on monitoring.

Scheduled

We will be undergoing scheduled maintenance of our database infrastructure for app and /query.

This includes a scheduled failover of our writer instance which will cause a slight increase in error rates during that time, which usually is just a few seconds. Our services will retry most of the requests.

We will notify once this is done and post updates if necessary.
