Locations were Active Directory service is going to be recovered following a disaster is very distributed. If a complete hub site (Data Center) fails then the other sites will collectively take over the Active Directory service load automatically. This is done by
Windows automatically. Windows chooses the closest logon server based on the fastest reply.
