A power shutdown is scheduled for this Saturday, July 11th to enable necessary maintenance on the Lab’s power distribution system. The power shutdown involves several buildings, including the 50 complex, which houses the Lab’s central IT systems.
Most IT systems will be offline from Friday, 7/10 at 5:00pm through midday on Sunday, 7/12. We expect most systems to be available by Sunday night but some systems will not return until Monday midday.
If you are in a building impacted by the outage (see below), there will be no network connectivity inside your building or access to the internet during the power outage. In addition, you are strongly encouraged to shut down all computing equipment before the outage. Computers and equipment are easily damaged by power outages.
We expect the following systems to be AVAILABLE throughout the outage:
However, in any power outage, there is the possibility that backup power systems will not function as expected. With the exception of www, today, newscenter, and status, it is possible that the services above may also be unavailable if backup power does not come on.
The following systems will be OFFLINE from Friday night until Sunday night (sub-bullets are examples of services, not all inclusive lists):
These buildings have different power outage windows on Saturday. However, given the various dependencies and pre-outage shutdowns, customers in these buildings should assume no network connectivity from early Saturday to early Sunday, even though it is expected the outage will be shorter.
