We will be upgrading our production infrastructure Sunday, September 20, 2020 @ 2:00 PM EST.
While we do not expect there to be any downtime, you may experience degraded performance during this time. We expect the maintenance to be completed by 6:00 PM EST, and we’ll post an update when the upgrades are complete.
We appreciate your patience.
As always, please don't hesitate to let us know if you have any questions.
