NCEDC Outage Jan 1-4, 2021

December 16, 2020

Between January 1, 2021 00:00:00 PST to January 4, 2021 23:59:59 PST the NCEDC will have reduced services or be offline. During that time, availability of the NCEDC web site and web services will also be affected. For several days after the outage, some requests for recent data may fail or return incomplete data, as BSL staff restore systems and archive missing data as it becomes available. This planned NCEDC outage is due to upgrades on the power systems at the UC Berkeley data center.
