I've done some research into the issue and was able to compile some information here:

I also have quite a bit of historical trace routes and ping checks showing latency on the host end of the network. The goal is to raise awareness about the issue. If enough feedback comes back on the fiber and server companies, they will optimize and upgrade their connections or Square will give us the ability to re route around them completely.
With IT businesses, it's common practice to not address an issue until the building is on fire. Until that happens, I don't expect a whole lot of movement.
