This page tracks Internet Exchanges (IXs) and broadband performance across Arizona. IXs are where networks meet to exchange traffic directly, and their presence in a state is a key indicator of its digital infrastructure maturity.

Internet exchanges reduce latency by keeping local traffic local. Without a nearby IX, data between two networks in the same city may travel hundreds of miles to a distant peering point and back. Low latency is increasingly critical for AI workloads, where model training, inference, and distributed computing all depend on fast data exchange between facilities.

Frequently Asked Questions
What is an Internet Exchange? ▾
An Internet Exchange (IX) is where multiple networks connect to exchange traffic directly, rather than routing through third parties. This reduces costs, improves performance, and lowers latency for end users.
IXs are typically housed in carrier-neutral data centers where no single network has control, creating a level playing field for all participants. Networks connect via switches and exchange traffic through peering agreements. A single IX may have a physical presence in multiple facilities across a state or region.

What is the source of this data? ▾
IX infrastructure data on this page is sourced from PeeringDB, a freely available database of networks and interconnection facilities maintained by the global network operator community. PeeringDB data is self-reported by network operators and facility owners.
Broadband performance data (download speed, upload speed, and latency) is sourced from Speedtest® by Ookla® open data, aggregated quarterly at the state level.
How many Internet Exchanges are in Arizona? ▾
As of the latest data, Arizona has 7 Internet Exchanges present across 15 facilities, with 165 unique networks physically connected.
These numbers are updated monthly from PeeringDB. See the chart above for historical trends.
Why does Internet Exchange location matter for Arizona? ▾
The physical location of Internet Exchanges directly impacts network performance, cost, and resilience for users and businesses in Arizona:
- Latency: Local IXs keep Arizona traffic local, reducing round-trip times
- Cost: Direct peering at local IXs reduces transit costs for Arizona ISPs
- Resilience: Multiple local interconnection points prevent single points of failure
- Economic development: IXs attract network investment, data centers, and digital businesses to Arizona
Without local IXs, Arizona traffic may be "tromboned" through distant cities, adding latency and cost.
Why are internet exchanges important for AI inference? ▾
Real-time inference and edge inference workloads require the lowest possible latency to deliver instant responses. Internet exchanges provide direct peering between networks, minimizing the number of network hops and reducing round-trip time.
This is critical for real-time inference applications like conversational AI and autonomous vehicles, as well as edge inference deployments that process data closer to end users rather than in centralized cloud data centers.
What is the average internet latency in Arizona? ▾
The average fixed broadband latency in Arizona is currently 16 ms, based on Speedtest® by Ookla® open data. Latency measures the round-trip time for data to travel between a user and a server. Lower values mean faster, more responsive connections.
States with more Internet Exchanges tend to have lower latency because traffic can be exchanged locally rather than being routed through distant cities. See the chart above for Arizona's historical latency trend alongside IX growth.
Which cities in Arizona have internet exchanges? ▾
Arizona has Internet Exchange presence in 5 cities: Chandler, Phoenix, Scottsdale, Tempe, Tucson.
Each city page shows which networks are physically present and which additional networks become virtually accessible through IX peering. See the cities list above for links to detailed data.
Which Internet Exchanges (IXs) are in Arizona? ▾
Arizona is home to 7 Internet Exchanges, including: Ninja-IX Phoenix, DE-CIX Phoenix, Global Peer Exchange, Digital Realty Phoenix, 48 IX, TUSIX, AZIX. Each IX enables networks to peer directly, reducing latency and transit costs.
How does Arizona's IX infrastructure compare to neighboring states? ▾
Arizona currently has 7 Internet Exchanges. Here's how neighboring states compare:
- California: 29 IXs, 15 ms avg latency
- Colorado: 5 IXs, 15 ms avg latency
- Utah: 5 IXs, 11 ms avg latency
- Nevada: 4 IXs, 16 ms avg latency
- New Mexico: 1 IX, 26 ms avg latency
