So there is a bit of a disconnect between what the web page says and reality. It seems depending on your area if you are between phases you won't get monthly status updates. I'm in San Mateo as well and in the same area ~26th and El Camino and this was the last status update from March:
Sonic's team is reviewing all the necessary requirements needed to begin engineering in your neighborhood. After this, our teams map out the exact placement of fiber in your neighborhood. This is an exciting (but often lengthy) phase. Because of this, we will cut back on communications and will reach out when we move into the next stage of your fiber build. We appreciate your patience.
Please tell your friends, family, and neighbors to sign up too!
Thank you for your support. If you have any questions, please call 1-707-757-7368.
Apparently this means zero communication until the construction phase starts. It's far from ideal and I would like something (email, status page, etc) with a rough ETA or even just a 'Yes we're still working on things' would be great. I actually called in last week and talked to a Keilani in CS about cancelling my pre-orders for both my home and office pre-orders. She was very nice and when I gave her the reasoning (zero communication) she said first tried to reach another department to see if there was an update to be had and then she said she would bring it up in one of their weekly meetings. I ended up not cancelling that day. She said that engineering can take 9-12 months and so the latest to expect an update would be around February/March next year. I do see them making progress in other areas of San Mateo, including my parents house and I have an install scheduled there for 10/29. So basically if you have the patience you can wait but don't expect any updates until construction starts(despite what the website says). Otherwise go with another option. I do know that Wave (my current provider at home and work) is working on their own fiber network as well so it will get here at some point from someone, the wait just sucks.
