Hello,

there was a fedorainfracloud outage yesterday that caused all the data volumes that Copr uses to be mounted read-only. We actually caught this problem yesterday on copr-fe but that was only a part of it, which we didn't realize until today. All cloud instances were affected by the ro remount and they are all finally fixed now.

We are sorry for rather long Copr unavailability at the time
Copr team
