Service updates - routine maintenance

Tonight (Amsterdam Local time), starting from 22:30 we will be doing routine monthly maintenance (operating system updates etc). Additionally we will be updating services like Nextcloud, Diaspora, Lufi, Framadate, Etherpad and Ethercalc, and Taiga. So expect short downtimes during which we will be working on upgrades. Note! Nextcloud update, since we want to make a proper backup (just in case) might take about an hour.
