Phoenix Residential Internet Coverage
Living in the Valley of the Sun, you have access to some blazing fast internet services. CenturyLink offers speeds up to 1 Gbps (1,000 Mbps) in some areas, and Cox Communications reaches speeds up to 300 Mbps. Those speeds are both dramatically faster than the FCC (Federal Communications Commission) broadband standard of 25 Mbps, so you should have no problems with online gaming or streaming in 4KHD, even with a large family.
Both CenturyLink and Cox, the two biggest Internet Service Providers (ISPs) in the Phoenix area, offer service to virtually the whole valley. Plus, a few other providers have smaller service areas sprinkled throughout the city. So, while most of Phoenix can get internet service from CenturyLink or Cox, there may be additional options in certain neighborhoods.
The CenturyLink service area covers most of Phoenix and Mesa. It stretches from Creek to South Mountain and from Sun City to Apache Junction. But it misses the Salt River Reservation.
Cox offers internet service across virtually the same area as CenturyLink in Phoenix, but the coverage areas diverge outside the city.
Mediacom also offers internet service in a few neighborhoods in Glendale and Mesa.
