Couple years ago.
Shortly after Verizon did a major upgrade to get FIOS installed every where in the Tampa Bay area.
They sold the FIOS side to Frontier.

At the same time Brighthouse sold to Spectrum.

I do know when Verizon was expanding FIOS they got in trouble in Florida with the state Public service commission that governs all utilities.
They took all the copper wire techs and used them for FIOS.
Which broke some kind of ruling that phone service for copper installs would have a outage less than 24 hours for phone service.

There is no such thing as stupid questions.
Just stupid answers.
