[Engineering] Additional European-appropriate MediaWiki train window starting week of July 9th (also SWAT change)

[Marko Obrovac]

Hello Greg,

I think this is a great initiative and will surely ease work for all people
working on the positive spectrum of UTC :)

One question/clarification, though: deployment windows have traditionally
been pinned to SF time (wrt DST changes, concretely), but in your email you
list them in CEST/UTC. Does that imply that these slots are pinned to
Europe's DST, UTC or will they stay pinned to pacific DST?

Cheers,
Marko
