Outgoing[edit]

Callouts[edit]

  • [RelEng] After several failed attempts to rollout wmf.28, we abandoned the release and moved on to wmf.29. This was done because (1) wmf.29 is a superset of code in wmf.28 (2) we need a stable base to rollback to and there was not enough time to determine wmf.28's stability.

Incoming[edit]

Team Business[edit]

Incoming/Needs attention[edit]

  • Observability is moving Icinga to victorops. I mentioned that it might be good to have a training with them where we can ask questions (like the dumb question I asked: Are you talking about nagios? I get nagios alerts, is that affected? No.)
    • Interested? Put your name here (If you get alerts you ought to go -- Mukunda, Antoine(?)):
      • Antoine
      • Mukunda
      • Brennen
      • Jeena
  • 2021-02-10: Brennen demos logspam-watch!!!
