Just curious where the 2gb service is available right now
Availability in your area? You should be able to "shop" within your Cox account.
As per here looks like only AZ has 2Gbps service as of right now. Also, you need to use a PW8 Panoramic gateway, however that may change in the future.
According to the Plans page, you'll need fiber connected to your house, aka FTTP (Fiber To The Premises) or FTTH (Fiber To The Home)
Did you read the thread I posted? It showed someone(causefx) posting 2Gbps/100Mbps service over DOCSIS/HFC. It was also confirmed by _Luke, who is a employee. Most 2Gbps service is fiber but it is available over HFC in some parts of AZ.
No, I didn't read the thread you posted. I guess we'd need to define "2 Gbps." Is it 2 Gb up and down or just a "hybrid" 2 Gb? I think the attraction to 2 Gb would be the upload but capping at 100 Mb seems like a scam.
