CenturyLink – Best Downtime Compensation

PROVIDER SCORE: 3/5

No one wants to deal with constant Internet outages. As little as an hour of internet interruption could mean lost productivity and hundreds or thousands of dollars in lost credit card sales or missed customer orders. Most internet providers have very low downtimes, but CenturyLink provides another layer of reliability by crediting you one day of DSL service for every thirty minutes of downtime your business suffers.

For smaller businesses, this added incentive can be critical when internet outages prevent revenue streams from increasing.

✓ Best For: Not For: 
Businesses that can’t afford internet interruptions
People needing excellent customer support
Flexible contractual commitments
Businesses that would suffer from a 1 TB monthly data cap

Availability: 3/5

Bandwidth: 3/5

As with most ISPs, speeds vary by area and depends on the infrastructure. CenturyLink’s DSL bandwidth runs up to 140 Mbps, which allows employees to simultaneously conduct online tasks.

Customer Service: 3/5

How to Choose Your Provider

Evaluate speed options

DSL speeds can vary from one internet service provider to the next. It’s best to compare more than one business DSL provider in your area (if there’s more than one) to determine the best bandwidth offer. Choose a higher speed tier than you think you’ll need — as your business grows, you may need more bandwidth.

Prep your home for DSL

If your home or business is not wired for DSL service yet, your service provider will send a technician to install the product. Make sure the area where the cables will be run is free and clear so the technician can access them quickly. Choose a central spot, so a connected router can transmit wifi throughout the property.

Test your speeds

Once you know the speed your ISP claims you’ll receive, test your internet speed regularly to ensure your service isn’t declining in bandwidth. If you notice a decline in your company’s DSL speeds, contact your service provider right away so you can receive guided troubleshooting to pinpoint and fix the issue.

Consider fiber or cable

Some DSL internet providers offer more than one type of internet service. Fiber is the fastest form of internet service today. Cable is similar in speeds to DSL, but it can be affected if others in the area are online with everyone in a neighborhood sharing the same bandwidth. 

If you have the option to subscribe to fiber, it will be well worth it. Fiber speeds are as high as 1,000 Mbps, compared to a mere 100 Mbps for some of the faster DSL internet packages.
