According to the official GPS testing (interference) website, there were tests at China Lake scheduled for sometime(s) on August 18-20, 2015. I think that Menlo Park is somewhat under 300 NM (nautical miles) from China Lake (depending on exactly where the test was located), and the expected interference range was about 252 NM. So you might have been at the edge of the affected area. See:

I don't see any satellite outages in the official report:

And note that except for certain government tests and operations, GPS
jamming is illegal, and violations are prosecuted:
