Qubes discourse forum was read-only for some time (less than one hour). Logout was forced. Some messages on missing configuration for administrator email has appeared.
I wonder if this was a planned upgrade. Since Qubes is a security oriented project, it would be a good practice to announce upgrades before performing the actual upgrade.
I didn’t receive any forewarning. My guess is that it was the Discourse project or the forum’s hosting service.
I’d be cautious about trying to apply such strict standards to external infrastructure like the forum (see here). If we tried to do that, we likely wouldn’t be able to have an official forum at all, since the overhead (i.e., costs of adhering to such strict security requirements) would likely be too burdensome for the project on top of everything else.
