[arch-devops] Maintenance window for luna

Hi all, tomorrow around 22:00 CET, the server that hosts forums, wiki and AUR will be offline for planned maintenance. The downtime will take up to 2 hours; the plan is to reboot it into linux-hardened, then see if it is possible to switch from Percona to MariaDB (and if the mysterious crash from the past still happens, gather debug data for reporting it upstream). Sorry for the inconvenience, Bartłomiej
