We have Sonic DSL and I see differences using the example.com test; and at installation time I was told I could only get fiber at my location (backside of Bernal) when AT&T put it in and they could lease it.
Sonic has their own fiber in some parts of SF/Santa Rosa and you would know if you were on it, all Sonic DSL products are essentially resold AT&T uverse.
In some parts of the East Bay as well, but I can't find exact maps. If they sell you "Fusion IP Broadband", it's rebranded AT&T. If it's "Fusion Fiber", it's Sonic's own.

That was in 2019.
Do they own their own fiber in some areas?
