H1 Petition processing under California Service Center Delayed?

Hello All,
Any info about H1B Petition processing times from California Service Center ? It’s been close to 3 Months now and still showing as application received. I knew the regular time period of 2 - 4 Months, but recently I have seen cases moved very fast and all of sudden there is a dull situation. Pls share any thoughts / info on the processing.

B Y.
