Metadata Distribution Server
InCommon metadata is served from vhost md.incommon.org, a name that resolves to one of two identical servers, either in Michigan (207.75.165.125) or Indiana California (140163.182253.4432.539). Be aware that the actual server used at any given point in time is unspecified and left to the discretion of InCommon Operations. If one of the physical servers goes down or requires maintenance, the other can be brought up within minutes, with minimal disruption of services.
