Between 04:30 and 05:30 UTC on 2018-02-28 (in a little under 24 hours) we’ll be upgrading the infrastructure that runs the snap store. All snap store services will be unavailable for a few minutes at a time during this window.
We’ll update this thread when the upgrades are complete.
I see a lot of "Internal Server Error"s on build.snapcraft.io at the moment (every other request or so) and the maintenance window still 20 or so hours out. Something going on?
