Yes, this site says I have Cox and Comcast in my zip code. I can assure you that Comcast is not doing cable internet business in my zip code or anywhere near my zip code. I don't believe they have a presence anywhere in the county.

Also the information blurb at the bottom says I have a fiber provider, but none are listed.

Finally, it's missing some local providers which I am positive exist; our local power/water provider also provides Ethernet to local business and some residential areas, but it's not listed.
