[rdo-dev] [infra] Planned maintenance on DLRN DB on Thursday, Sep 24th

Hi, It looks like the previous maintenance on the DLRN database did not solve all issues, so we need to run some more maintenance activities to fix the DLRN DB replication next Thursday, September 24th, at 9:00 UTC. These activities require the main DLRN DB to be set to read-only mode for a while, so the DLRN API will not allow write operations (reporting results or promotions) during that period. We expect the maintenance operation to last less than one hour. If you have any question or concern, please do not hesitate to contact me. Regards, Javier
