CHPC - Notice history

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.

Rocky Mountain Power has just notified us of a planned power outage to the Downtown Data Center and vicinity this Sunday, March 16, at 9am to address some urgent electrical changes for the city. The CHPC systems with power backed up by generators (the Protected Environment, network, data storage, and virtual machines) will be fine, but the systems with battery backup only will need to be shut down. Therefore we will shut down the general environment clusters lonepeak, kingspeak, notchpeak, and granite at 8AM on Sunday March 16. We estimate these servers will be down for several hours.
