[AG-TECH] Argonne AG bridging infrastructure down

[turam at mcs.anl.gov]

Following planned power maintenance in the room where the Argonne Access Grid servers machines reside, the Argonne Bridge Registry, Bridge, and accessgrid.org are down. We will restore these services when the required server infrastructure becomes available again.

In the meantime, users should be able to use unicast bridges, but will be unable to update their list of unicast bridges. Bridge administrators may notice that their bridges are unable to communicate with the registry.
