According to our CNET experts, Optimum is the best internet provider overall in Flagstaff for most households. The provider offers broad coverage in Flagstaff and fast speeds of up to 1,000 megabits per second. However, Optimum service isn’t available everywhere in Flagstaff, so Quantum Fiber is also a solid pick, depending on what’s available at your address.
If you’re looking for the lowest price available, Flagstaff’s cheapest internet is Optimum’s $40-per-month 300Mbps plan with equipment included. Flagstaff’s fastest internet speed is a tie between Optimum’s 1,000Mbps cable plan and Quantum Fiber’s 940Mbps plan. Quantum Fiber offers equally fast uploads, but availability is extremely limited.
Flagstaff internet providers, such as Optimum, may offer lower introductory pricing or streaming add-ons for a limited time. Many, including Quantum Fiber and Bluespan, tend to run the same standard pricing year-round.

How fast is Flagstaff broadband?
Despite a lack of multi-gig options and fiber internet, Flagstaff turned in a decent performance in a recent Ookla speed test report. (Ookla is owned by the same parent company as CNET, Ziff Davis.) The city in the pines pulled down a median fixed internet download speed of 273Mbps, which is more than Arizona’s speed test average as a whole. Optimum checks in as Flagstaff’s fastest provider, which makes sense considering it has little competition. CenturyLink’s widespread but slow DSL network doesn’t put up much of a fight and Quantum Fiber is hard to find.

What’s a good internet speed?
Most internet connection plans can now handle basic productivity and communication tasks. If you’re looking for an internet plan that can accommodate videoconferencing, streaming video or gaming, you’ll have a better experience with a more robust connection. Here’s an overview of the recommended minimum download speeds for various applications, according to the FCC. Note that these are only guidelines and that internet speed, service and performance vary by connection type, provider and address.
0 to 5Mbps allows you to tackle the basics: browsing the internet, sending and receiving email and streaming low-quality video.
5 to 40Mbps gives you higher-quality video streaming and videoconferencing.
40 to 100Mbps should give one user sufficient bandwidth to satisfy the demands of modern telecommuting, video streaming and online gaming.
100 to 500Mbps allows one to two users to simultaneously engage in high-bandwidth activities like videoconferencing, streaming and online gaming.
500 to 1,000Mbps allows three or more users to engage in high-bandwidth activities at the same time.
How CNET chose the best internet providers in Flagstaff
Internet service providers are numerous and regional. Unlike the latest smartphone, laptop, router or kitchen tool, it’s impractical to personally test every internet service provider in a given city. What’s our approach? For starters, we tap into a proprietary database of pricing, availability and speed information that draws from our own historical ISP data, partner data and mapping information from the Federal Communications Commission at FCC.gov.
It doesn’t end there: We go to the FCC’s website to check our data and ensure we consider every ISP that provides service in an area. We also input local addresses on provider websites to find specific options for residents. We look at sources, including the American Customer Satisfaction Index and J.D. Power, to evaluate how happy customers are with an ISP’s service. ISP plans and prices are subject to frequent changes; all information provided is accurate as of publication.
Once we have this localized information, we ask three main questions:
Does the provider offer access to reasonably fast internet speeds?
Do customers get decent value for what they’re paying?
Are customers happy with their service?
While the answer to those questions is often layered and complex, the providers who come closest to “yes” on all three are the ones we recommend. When selecting the cheapest internet service, we look for the plans with the lowest monthly fee, although we also factor in things like price increases, equipment fees and contracts. Choosing the fastest internet service is relatively straightforward. We look at advertised upload and download speeds and consider real-world speed data from sources like Ookla and FCC reports.

What’s the final word on internet providers in Flagstaff?
Flagstaff can be a tricky place for internet. Most residents will choose to go with Optimum thanks to availability and a gig speed tier if you need zippier downloads. It also offers one of the most affordable plans in town at the 300Mbps level. Give weight to Quantum Fiber and its symmetrical speeds if you happen to live in a pocket of coverage. If Optimum doesn’t work out for you, then check into T-Mobile’s 5G home internet offerings. After that, get in touch with Bluespan or another fixed wireless provider. Rural and remote homes may need to investigate a fallback option like Starlink satellite internet.
