All Services
Operating system updates; reboots will be required. The usual HA mechanisms will be used, but some services will experience brief outages.
All systems with IPv6 addresses defined in DNS will become dual-stacked IPv4/IPv6 on both public and private networks. Some individual services may not necessarily accept IPv6 connections, depending on the software.
