    Facilities will be performing an electrical shutdown at Nevis Laboratories, Sunday 06/13/2010, from 8AM-4PM.

    We anticipate our network equipment at Nevis to lose power during this time. Therefore, Nevis will lose network connectivity to the outside world.

    We also anticipate that our Qwest Commodity Internet connection at Nevis to go down as well. Lamont-Doherty Earth Observatory (as well as Nevis) use this connection as their primary connection to the Commodity Internet. We anticipate Lamnot's Commodity Internet traffic to be re-routed to our primary Commodity Internet connection at Morningside, during the electrical shutdown.

    In addition, during the listed time, the Nevis voice tie line service to Morningside Campus will also be unavailable.
