On Thursday, March 19, 2020 Governor Gavin Newsom announced a statewide Executive Order for people to stay at home. The directive went into effect immediately. A copy of the Executive Order can be found here.   

Notably, the Executive Order references the  guidance issued by Cybersecurity and Infrastructure Security Agency (CISA) within the U.S. Department of Homeland Security with an initial list of “Essential Critical Infrastructure Workers.”  A copy of that memorandum can be found here.  In addition, the Order states  the Governor in consultation with CAL OES, may designate additional sectors as critical.
