SWAT deploy slot time changes (and adding European mid-day slot)

Greg Grossmeier-2
tl;dr: Starting the week of August 22nd there will be 3 SWAT deploy
windows: at 13:00, 18:00, and 23:00 UTC (6am, 11am, 4pm PDT).

Hello all,

I'm pleased to announce that after being heavily SF-focused for a long
time we're adding a Europe-focused (and slightly better for Asia/India)
SWAT window[0] starting on August 22nd[1].

This new SWAT window follows a couple changes to the SWAT process[2] and
scap tooling[3] which make SWAT deploys less risky and stressful for all
involved.

We hope this additional window will make the lives of all teams and
volunteers (at least slightly) better.

<3,
Greg and the Release Engineering Team

Reminder: This change begins this coming Monday, Aug 22nd.

If you would normally use the 9am Pacific ("morning SWAT") you'll either
go 3 hours earlier (6am Pacific/13:00 UTC, "European Mid-day SWAT") or 2
hours later (11am Pacific/18:00 UTC).

Hello,

It went all fine. The canary check and mw1099/X-Wikimedia-Debug make it
a breeze to do the deployments.

We had 8 patches which kept us busy, I am hoping to do actual training /
levelling up when there are less patches to push.

cheers,
