I wonder how this fire started?? I feel so sorry for the companies that were affected by this fire. I assume they will cease to exist. This is so sad. If anyone knows who or what caused this fire, please share this information. Thanks.

I just heard about it. Why do so many fires begin between 3 - 5am? On a Christmas morning? Santa delivering hot coals? Doubt it. Lots of really old buildings mysteriously catch fire. No restaurant, only Judo, hair and nail, Tailor shop in that building.
[Portion removed]. In October, 2013, I was victim of an arson in Palo Alto. No perpetrator caught. In 2014, seven arson jobs recorded in Sunnyvale. It's underreported crime.

[Portion removed] And, how long is Eastbound El Camino expected to be closed? El Camino Eastbound is TOTALLY closed on the East side of San Antonio Rd. San Antonio is unaffected except for turns in the Eastbound direction and also possible the East pedestrian crossing. You will have to take California or cut through Los Altos to avoid what will be a huge traffic jam. I drove thru there at 830 AM this morning (Wed 27) with virtually no traffic and it already was backing up.
