The incident has been resolved. All our services are back online.

We are currently experiencing a service outage affecting Dashboard and
AltGuard. Website, Internal API and Health Monitor may be degraded as a
result.
The cause has been identified as a DNS misconfiguration introduced during a
recent migration of our DNS provider: several hostnames stopped resolving,
which prevented the affected services from being reached. Corrected records
are being published now.
Moddy Bot and Social Notifications are not affected.
