Update
Upgrades were completed succesfully, and all services should be back online as of now (30 minutes ahead of expected)!
Original
Today at noon local time (2016-11-08T18:00:00Z-2016-11-08T19:00:00Z) the CPT server will go down for maintenance. We are adding new RAM into the server which should alleviate many of the issues our users have been experiencing lately.
We apologise for any inconvenience, but the benefits of this upgrade will significantly outweigh the negative impact of temporary unavailability.
