Step one - Feb 17 at 6:00AM EST - This step is expected to be transparent as existing network connections through the firewall are expected to remain intact.

Step two - Feb 18 at 6:00AM EST - This step will break existing network connections through the firewall. Users will need to re-establish network connections if they break.
