I want to kind of close out this thread. I appreciate everyone’s input. I think in a perfect world, switching to cable internet would be the more ideal solution. Neither company was willing to waive any fees, at least not without a fight, so switching providers is kind of a last resort situation.

However....

The problem does seem to be resolved. Time will truly tell, but the internet has been up and running without a single hiccup since the tech was here Wednesday. Apparently, when we upgraded to a higher speed, the CO tech at the time did a lazy hack to bump the speed without taking the time to make sure his parameters would be stable. The other CO tech totally scrapped his build and made a new one from scratch that seems to be keeping the connection stable. For now the problem is solved, and everything seems to be working as it should. I know DSL (or in our case, VDSL) is a dated technology, but it is sufficient for our needs.

Thank you all for your help, as always I really appreciate it.
