Not sure if this factors in, but Analytics will be having an offsite in NYC the week of Sept 16 - 22. Luca and I will be less available during that week.

Hello everyone,
I hope I have included all the relevant teams, please add anyone I might have forgotten
As you probably know, Ops has decided to perform a datacenter switchover this quarter. It's already close to 1.5 years[1] since the last one and we 've been wanting to do more like 1 per year. Our tracking task is https://phabricator.wikimedia.org/T199073 and work has already started in various sub areas. One thing that we need to decide on is the actual dates. Having looked at the various possibilities and the work that needs to be done up to that point, we have come to the conclusion that the weeks of
- 17-21 Sept 2018
- 24-28 Sept 2018
for the switchover and
- 08-12 Oct 2018
- 15-19 Oct 2018
for the switch back.
Keep in mind that this time around we want to do at least 3 weeks, 1 more week than the previous switchover, so if we do choose the week of 24-29 Sept for the switchover, we have to do the week of 15-19 for the switchback.
We also need to decide on the actual time of the date of course. So this is your invitation to a scheduling meeting about discussing that.
Remembering the previous switchover's scheduling meeting I think that coming up with a proposal that can be discussed individually/per team before the large meeting can be beneficial.
So here's a proposal that just copies the previous switchover/switchback schedule [1]
Switchover:
Services: Tuesday, September 18th 2018 14:30 UTC Media storage/Swift: Tuesday, September 18th 2018 15:00 UTC Traffic: Tuesday, September 18th 2018 19:00 UTC Mediawiki: Wednesday, September 19th 2018: 14:00 UTC
Switchback:
Traffic: Tuesday, October 9th 2018 19:00 UTC (and maybe some prep work on Monday) Mediawiki: Wednesday, October 10th 2018: 14:00 UTC Services: Thursday, October 11th 2018 14:30 UTC Media storage/Swift: Thursday, October 11th 2018 15:00 UTC
Now as for the meeting date, google for this week suggested August 1st 14:00 UTC as the time with the least possible conflicts, so here it is.

FYI, we just had a meeting about this, we did factor it in and do consider it a dealbreaker. So we proposed moving it 1 week earlier, that is the Week of Sept 10 - 14. I hope this helps. On Tue, Jul 31, 2018 at 8:46 PM Andrew Otto otto@wikimedia.org wrote:
