Hi all

There is a planned datacenter switchback next week scheduled for Tuesday, October 27th 2020[0].

To avoid creating problems for our SREs we'll be skipping the train for next week -- the week of 2020-10-26. Additionally, we want to avoid deploys for a full 24 hours following the switchover. This means no deploys next Tuesday (2020-10-27) and no deploys Wednesday (2020-10-28) until after 15:00UTC.

The deployment calendar is up-to-date[1].

As we head into the holiday season, I've added a list of foreseeableĀ train disruptions to the bottom of the Deployments Calendar[2].
