Incoming/Needs attention[edit]

https://phabricator.wikimedia.org/T277507 https://phabricator.wikimedia.org/T118212

    • Dan: anti. Not doing anything with the branch until Tuesday
    • Brennen: In favor of not having things go out right away
    • Lars: Automate to testwikis
    • Action: Thcipriani: to decline

Instead of using groups, use traffic ratios, e.g. 1.36.0-wmf.35: 90% 1.36.0-wmf.36: 10%

  • Ahmon: during train log triage meeting, it was mentioned that it would be nice to have enwiki tested earlier in the week. Proposal: instead of groups we move towards percentages. enwiki gets exposure right away (would hopefully bubble up quickly). Iterate with fixes until we hit 100%. Wikiversions, instead of looking up wikis, could use a random number to make a balance
  • Mukunda: some servers have 1 version, some servers have another, depend on load balancer
  • Greg: servers as a proxy for percentages?
  • Mukunda: multiversion is touchy, but it might be a good thing to kill off
  • Brennen: great idea, would have to surface externally
  • TODO: Ahmon to file task

Train Go/No Go: https://docs.google.com/document/d/1GXC_Bf9iAvme58euBLQSMMxl1_ojbr32bjcHH6q1wKE/edit#

  • Brennen: weekly cadence still?
  • Lars: Timezones may be a problem
