What Causes Outages?

Losing power or Internet may seem unlikely, but interruptions happen. From weather to user error, safeguard your business against these five common causes of outages:


Thunderstorms, hurricanes, tornadoes, snowstorms, wildfires and more can cause Internet and power loss, resulting in unexpected downtime for your business.

Human Error

Accidents happen—especially when it comes to technology. Whether that means misusing hardware or an unplugged chord, human error can cause a loss of connectivity.

Equipment Failure

Old or improperly maintained equipment can also cause outages. Keep equipment updated to reduce the risk of an outage.

Overloaded Networks

A strained network can reach its limit, resulting in slower Internet speeds or a complete outage.

Cut Cables

Construction, outdoor landscaping and other outside factors can inadvertently cut a line and disrupt your business.

Internet Backup FAQs

Backup Internet for business is a safeguard against service interruptions. In the event that your business loses internet access, backup internet, such as our Net Assurance product, is available to keep so you stay connected.​

If your business loses internet service, Net Assurance, our backup internet solution, automatically connects to an LTE internet provider.​

LTE is a term used to describe the technology that allows devices, like cell phones, tablets and more, to connect to the internet.​

Internet failover is a standby internet solution that automatically turns on if your primary internet system fails.

Yes. If a Cox Business customer with a gateway and existing service loses internet access, their internet connection automatically switches to the LTE wireless network, with the exception of guest networks (which are disabled during backup service).​

Cox offers LTE backup for a low monthly fee. With LTE failover, keep your business operating in the event of unexpected network and power outages without paying for usage or purchasing expensive equipment. Contact one of our Cox Business representatives to ask about pricing in your area.

In the case your Internet is interrupted by a power outage, LTE backup automatically connects you to an LTE Internet provider in your area.

In the event of failover to LTE, the static IP address is not used. A dynamic IP address is used from the LTE network. The static IP will not be available until Cox Business Internet is restored.​

When you’re on LTE backup, you’ll be connected to the internet via an LTE network. Your speed will be limited to a maximum of 10/2 Mbps. Guest WiFi will be disabled automatically and devices with statically assigned IP addresses will not route over the LTE network — for example, devices with statically assigned IP addresses will not be accessible over the LTE network.​

No, you will not be charged for LTE wireless usage while on business internet backup. However, if your usage is high, Cox Business may reach out to offer feedback and help troubleshoot if need be.​

On business internet backup, you’ll experience between 1/0.5 Mbps and 10/2 Mbps. While nothing replaces the speed or reliability of your primary internet connection, business internet backup is intended to give your company enough connectivity to keep you operational during downtime, protecting your productivity and your ability to deliver for customers.​
