I so desperately wish it weren't abandoned. I hate that it's almost 2026 and I still can't get a fiber connection to my apartment in a dense part of San Diego. I've moved several times throughout the years and it has never been an option despite the fact that it always seems to be "in the neighborhood".
The worst part is it'd probably cost less than $100 of fiber and labor to splice something into your building, maybe $200-400 of gear to light it up, and you'd have a 10 gbps pipe back to some colo. It's more economical to run new fiber in most places these days, even if the local ISP knows exactly where all the old abandoned legacy lines are run, because of subsidization and basically scamming. The big companies like Lumen keep their knowledge regionally compartmented, legally shielded, and deliberately obfuscated, because if it became known that existing fiber was already run to a place they claim they can't serve, they can't get access to yet more funding for their eternal "service for the underserved" government money grift.
I stumbled on old maps that showed a complete coverage of fiber in my municipality, paperwork from a company that was acquired, and which in turn merged, then was bought out by one of the big 5 ISPs. When local officials requested information regarding existing fiber, this ISP refused and said any such information was proprietary. They later bid on and won contracts to run new fiber (parallel to existing lines which they owned, which still had more than a decade of service life left in them at that point).
I estimated that only around 10-15% of the funding went toward actual labor and materials, the remainder was pure profit. The local government considered it a major victory, money well spent.
That has nothing to do with fiber, it’s all about politics and a regulatory environment where nobody is incented to act. Basically, the states can’t fully regulate internet and the Federal government only wants to fund buildouts on a pork barrel basis. Most recently rural.
At the local level, there is generally a cable provider with existing rights of way. To get a fiber provider, there’s 4 possible outcomes: universal service with subsidy (funded by direct subsidy), cherry-picked service (they install where convenient), universal service (capitalized by the telco) and “fuck you”, where they refuse to operate. (ie. Verizon in urban areas)
The private capitalized card was played out by cable operators in the 80s (they were innovators then, and AT&T was just broken up and in chaos). They have franchise agreements whose exclusivity was used as loan collateral.
Forget about San Diego, there are neighborhoods in Manhattan with the highest population density in the country where Verizon claims it’s unprofitable to operate.
I served on a city commission where the mayor and county were very interested in getting our city wired, especially as legacy telco services are on the way out and cable costs are escalating and will accelerate as the merger agreement that formed Spectrum expires. The idea was to capitalize last mile with public funds and create an authority that operated both the urban network and the rural broadband in the county funded by the Federal legislation. With the capital raised with grants and low cost bonding (public authority bonds are cheap and backed by revenue and other assets), it would raise a moderate amount of income in <10 years.
We had the ability to get the financing in place, but we would have needed legislation passed to get access to rights of way. Utilities have lots of ancient rights and laws that make disruption difficult. The politicians behind it turned over before that could be changed.
