During our team meeting today we settled on the following timeline for shutting down the grid. I'm emailing here for posterity; Komla will take care of notifying our users.

* This week: prepare pywikibot migration solution https://phabricator.wikimedia.org/T249787%C2%A0 (Taavi + Raymond)

* Nextweek: media blitz (Komla) **emails ** wikitech site notice ** wikitech list email ** cloud-announce email ** wikitech talk pages

* Late Nov/Early Dec: commandline notification ** jsub + company are wrapped in some way to notify users about incoming shutoff

* Dec 14th: warning shot ** Tools owned by unresponsive admins or unreachable admins are stopped ** Tools run by unresponsive admins get their crontab entries commented out, and warnings inserted

* Feb 14th: grid is stopped entirely ** All tools stopped, new submissions prevented

* Mar 14th: grid infra deleted
