In early September, The Matrix Foundation homeserver went down.

I'm extremely proud of our SRE team. They had a Disaster Recovery Plan and monthly exercises to apply it, resulting in no data loss despite a 24h outage.

I've learned a lot about how to properly backup/restore a Postgres database when writing this post with SREs. We also learned how to better prevent and be resilient to human error.

Thanks all for the hugops during the outage!
