Beginning at approximately 10pm Arizona time and extending until about 2am the following morning, all servers will be unavailable while updates are performed. To find the time in your timezone, see here: http://everytimezone.com/#2015-3-30,-420,cn3 The entire server will be unavailable. The maintenance will consist of security updates for the underlying OS and a new permissions system for all servers. This is a substantial update and there are likely to be residual permissions problems after the updates are completed. Please bear with us as these are worked out. Thanks for your patience and understanding.
