@ordnung I've seen this exact issue in prod sooo, sooo many times and I still can't figure out what's wrong with the thing.
Ended up replacing it entirely for prod machines, but I'd still really like to know what's happening there.
There's some issue that looks the same, which sometimes (but not reproducibly) occurs when IPv6 addresses change while resolved is running, but I'm not sure if it's the same issue as the sudden/random hangs...
*sigh* :(
*hugops*, thanks for your time and effort!

@manawyrm @ordnung it stops resolving via DBus. Strace any affected network tool (curl) and watch it hang at waiting for systemd-resolved via the DBus (https://www.freedesktop.org/software/systemd/man/latest/org.freedesktop.resolve1.html). I have that issue constantly, every few days - tho only on my server. Restarting resolved doesn't really work, for some reason I need to change the config a bit, restart and test. Repeat if still broken
