Do I qualify for fiber, and how low can latency go on DOCSIS 3.1? (Royal Palm Beach, FL 33411)

Hi, I'm an Xfinity Internet customer in Royal Palm Beach, FL 33411. I play online games and want the lowest latency possible.

Two questions for an Xfinity employee:

1. Does my address qualify for Xfinity fiber (for example Gigabit x10)? If yes, what would it cost?

2. If I stay on DOCSIS 3.1, what is the lowest latency I can expect, and what should I do to get it? For example: is Low Latency DOCSIS enabled for my gateway, is my node on the mid-split upgrade, and would a newer gateway (XB8) help?

I can send my name and address by direct message. Thank you!
