From our hosting company:
We will be performing routine software updates on **Sunday, June 13, 2010** starting at 1500 UTC. This will include one update which will require the servers to be rebooted during which time all services will be unavailable — this typically takes ten to fifteen minutes for each server.
More information can be found at:

If you’re unable to access NS during this time, just wait 10-15 minutes before trying again
