I think AD partly uses it to point you to a closer DC or other server if available.

From TechNet:
Sites in AD DS represent the physical structure, or topology, of your network. AD DS uses network topology information, which is stored in the directory as site, subnet, and site link objects, to build the most efficient replication topology. The replication topology itself consists of the set of connection objects that enable inbound replication from a source domain controller to the destination domain controller that stores the connection object. The Knowledge Consistency Checker (KCC) creates these connection objects automatically on each domain controller.

A side note: if you are buying a new laptop anytime soon, get one with a backlit keyboard. It really helps you typing at 3AM in the dark. My work Latitude has it and it is wonderful at times like these.
