On Thursday and Friday, January 19th & 20th, we will proceed with a Portal update. This is a fairly major technology update which will cover the node.js version, but also major updates to node.js modules. The migration will be done in 2 steps and should be totally transparent with no down time. This is only a technology update; there are no new features. The first step will be done on 01/19 from 5am PST to 7am PST, and the second step will be done on 01/20, from 5am PST to 7am PST.
