[NTG-context] "Scheduled" downtime of the contextgarden server

Dear ConTeXters, There will be a "scheduled" downtime of the contextgarden.net server for maintenance reasons (the part that's hosted in Slovenia; that excludes wiki & modules, but includes the old distribution, buildbot CI, CTAN, TL pretest & w32tex mirror, ...) in one of the following days. It's not yet clear when exactly the downtime will happen (and all the lockdowns etc. make that even harder to predict) and I'm also not entirely sure how long it will take, this is just to give you a notice upfront. Mojca (PS: I hope that TL 21 won't need any further builds, else we can postpone this.)
