Between 23:00 and 23:59 UTC on 2017-08-13 (in a little under 48 hours) we’ll be upgrading the snap store’s storage systems to improve stability and performance. Snap uploads (including from snapcraft, build.snapcraft.io, Launchpad and Travis CI) will be unavailable for most of this window, and downloads will be intermittently unavailable while we perform parts of the upgrade.
We’ll update this thread when the upgrades are complete.
