    This is a planned downtime at the Downtown Data Center to perform electrical work for the new cooling system, and will impact the general environment clusters lonepeak, kingspeak, notchpeak, and granite. Parts of the protected environment including the redwood cluster may be shut down for system administration work as well. The electrical work by the DDC staff is expected to take the entire day on the 25th, and systems will be brought up the following day after the power outage and any system admin work is complete.
