Hello Leah,
Yes and no, not anymore.
>From Monday to Wed we had bad connectivity from LA to Sacramento, but different from your scenario, ping had a good latency but package loss was noticeable. 
After 2 days of phone chattery we managed someone to skip San Jose, San Francisco and the whole SF Bay area, routing us via Fresno-Modesto to reach Sacramento. Latency increased a bit but overall quality was restored.
So yes, somehow I can confirm there's something going on with apparent isolated issues on Bay Area, specially near San Jose. Seems isolated because from what I noticed on phone it was "only me". And now you.

> Thanks for your feedback!
