Due to the unprecedented PHP vulnerability today, I took the blogs down until Debian pushed a fix, as advised. (And also Quimby.)
They pushed a fix now, so things should be back to normalish. Except that the web server on Gmane is still down — I need to do further upgrades on that machine, so it’ll remain down for the time being. I.e., you can’t sign up any new mailing lists or Gwene RSS feeds, but that should be back up within a few days. (The news server itself and other services are up — it’s just the web part that’s down.)
