will be performing network-related changes today
starting at 8:00pm Thursday, March 4, 2021 EST
(1:00am Friday, March 5, 2021 UTC)
There is no plan for disruption, but simply the possibility of disruption if things don't go according to plan.
So this is just a heads-up so that you're aware of the possibility,
and that "it's us, not you" if you find yourself having unique trouble tonight.
edit: They just pushed their schedule forward by an hour, so the window now starts at 8:00pm EST instead of 9:00pm EST.
