We had already moved to Frontier Fiber from Optimum... We moved as soon as Frontier came to town... But had an outage in October due to a Fiber break to our house which Frontier seemed incapable of fixing... After 10 days without any progress, we ended up moving back to Optimum.

The only good thing is that as both Frontier and Optimum cover me with fiber, their prices are reasonable at $60 for 1 Gig.

Almost tempted to get two services... My Cisco router supports load balancing across two WAN links so it wouldn't be such a big stretch.
