Bad ISPs are bad. Here's what my ISP claims
Dedicated symmetrical fiber, so speeds never go down or change.
We do not block, impair, degrade, delay or otherwise inhibit access by our customers to lawful content, applications, services or non-harmful devices.
We do not prioritize our own content, application, services, or devices, or of our affiliates.
I will get 100% of my speed 100% of the time, if not, they will fix the issue. Since they do not oversubscribe their last mile, the only time I don't get 100% of my speed is when something is broken, and they're already fixing it.
