What is sad and VERY scary, is that this should never have been a problem. Public Safety agencies are not downloading cat videos or other nefarious websites.
WRT the Mendocino Complex fires (the Ranch and River incidents), CalFire is providing links to the Mendocino, Lake and Colusa County Sheriff's Facebook pages for information. So yes, the agencies are using Facebook, but to disseminate important information.
Living in the Sacramento area, I haven't yet found a resource like the weekly Disaster Preparedness amateur radio net, or WWCalif.com for timely information. Can you imagine losing these resources during the Blue Cut fire?
Peace my friends.
