The operational SkyView machines have been moved to a virtualized environment. The numeric IP address for SkyView has been changed to 126.96.36.199. This actually points to a load balancer on top of several virtual machines. The new machines are already being used inside Goddard, and the change should propagate throughout the rest of the web over the next day or so as domain name servers refresh their caches. The address skys.gsfc.nasa.gov points to the same location.
So far there have been no problems reported in the transition. All surveys and services, including the SkyMorph NEAT archive and VO access should be available. Please let us know if you notice any anomalies.
