At 22:27, one of our hypervisors lost access to parts of its disks. Amongst others, It impacted a deprecated front reverse proxy for applications and a front reverse proxy for add-ons (databases).
We moved the IP of one of the proxies. The other one, related to the application reverse proxy (18.104.22.168) couldn't be moved and is now unreachable. If you still use it, you should update your DNS records: https://www.clever-cloud.com/doc/admin-console/custom-domain-names/#personal-domain-names
The situation is stabilized. We still consider the infrastructure not fully recovered.
