2016 CIS Maintenace Weekends Schedule Proposal

CIS is proposing the following dates for maintenance weekends. These weekends can typically involve some amount of unavailability for lab systems, including e-mail, networking, etc. They do not typically affect MCS/CELS systems, but they can if the outage is related to networking.
At the moment, the following weekends are proposed. If you know of some critical work you have happening on those dates that would be adversely affected, let me know by July 2.
Proposed Dates:
November 6-8, 2015
January 15-17, 2016 (APS Maintenance period)
May 13-15, 2016 Network Maintenance (APS Maintenance period)
August 26-28, 2016
Thanks!
