What to know about backup internet in Phoenix
Phoenix is digging, and buried lines get hit
The City is building a 3.9-mile fiber-optic and traffic-device project on Deer Valley Road and 7th Street. Construction began in early 2026 and is expected to finish by late 2026. The city notes that traffic and pedestrian movement may be modified while access is maintained. Street work like this is one way a buried line goes down without warning.
Utilities have two working days to mark lines
Arizona law gives utilities up to two working days to mark underground lines after a dig request, and no one may excavate until marking is complete. Marked lines are much less likely to be cut, but marking isn't perfect, and a cut line leaves you offline until the provider repairs it.

Monsoon season runs June 15 to September 30

Cox lists a 4-hour service level agreement
Cox Business lists a 4-hour service level agreement on Phoenix business internet, plus dedicated fiber with symmetrical speeds up to 100 Gbps, depending on address. An agreement sets a repair target. It does not keep you online while you wait, and a second connection does.

What takes a business offline
Most outages start in the small things between you and the provider's network: a street crew hitting a buried line, a failed modem, a power loss at a node, a storm. Phoenix addresses are served by SRP or APS depending on location. SRP staffs its outage line around the clock at (602) 236-8888, and APS has an outage map. Nobody can predict which failure comes next, so the fix is a second path.
- Street and utility construction that cuts or damages buried lines.
- Power outages and storm damage during monsoon season.
- A failed modem or a bad connector.
- A provider outage that spreads across a neighborhood.
Starlink or 5G
A 5G backup uses a cellular modem and an antenna. It installs fast, needs no view of the sky, and handles registers, card terminals and phones well. Starlink uses a dish and its own network, so it avoids both your cable line and the cell towers. It needs a clear view of the sky and a mount.
Some sites run both. We test signal at the building before recommending either.
Failover without anyone touching it
A failover router watches your main line. When the line fails, it moves traffic to the backup within moments, and when the line returns, it moves traffic back. Staff do nothing.
We also choose what runs on the backup. Registers, card terminals, phones and cameras go first. Guest WiFi and streaming can wait, so a slower backup isn't swamped.
Placing the dish or antenna in Phoenix
Phoenix zoning allows roof-mounted satellite earth stations on primary structures of non-residential properties, subject to building setback. The code defines that class by size and doesn't say how a small dish is treated, so we ask the city instead of assuming. If your building is on the Phoenix Historic Property Register, exterior changes need a Certificate of No Effect or Appropriateness before a building permit. A roof mount also has to hold in monsoon wind, so we anchor and seal it for the weather.
Dust and summer heat are hard on outdoor gear, so the modem and router stay indoors in a ventilated space.
How an install goes
- Walkthrough of your current line, your rack and the roof or wall options.
- Signal test for 5G, or a sky-view check for Starlink.
- Mounting, cable and the failover router, scheduled around your hours.
- Live test: we unplug the main line and confirm the backup takes over.
- Service continues Monday to Friday, 8 AM to 5 PM.
Often paired with
A second line matters most when business phones run over the internet, security cameras record to the cloud, or guests rely on business WiFi. Our other Phoenix services are listed on the Enzo in Phoenix page.
