Rich and partial DC firewall migrations complete

On Sunday at 6am we migrated all of the networks on rich-rtr and the most of the networks on dc-rtr to Palo Alto appliances. With improved coordination and communication with other OIT units this time around, the migration went significantly smoother and most services were restored by 9am. The remaining networks on dc-rtr are for services managed by ITG and they will migrate on Thursday September 28th.
