Backing Up Broadband
By: John SheplerIn recent decades, broadband Internet service has transformed from an underutilized business tool to an essential infrastructure for most businesses. Both speed and traffic have increased manifold. So answer this question: "What if your broadband drops?"
We became silently dependent.The transition from traditional business processes to automated and digital communications has been gradual, with many companies not knowing what would happen if everything suddenly died. You know what happens when you run out of power. This facility is currently not operational. You already know what happens when your data center loses power. Your computer-based process is gone. If this is unacceptable, what have you done to ensure continued employment?
Risk of single point failure
How are battery backup hookups and diesel generators the same for electric power? This is one or more redundant communication lines. If only one broadband line feeds your network, you have what is known as a "single point of failure". This is where any type of failure can put you out of business. You can have all kinds of computers, printers, servers, backup batteries and extra trained people to handle any priority tasks no matter who is sick. If your business is an online business and there is no way to connect you and your customers, there will be no profit.
Start with the best line you can find
There are broadband services and then there are broadband services. They actually fall into two categories. There are telecommunications services that are designed for high reliability and often come with a service level agreement, a type of performance guarantee. Then there are "best effort" services that are designed to cost less and come with no performance guarantee Which one do you think is best for your mission critical events?
Examples of highly reliable dedicated services are telecommunication-based services such as T1, DS3, SONET, Ethernet over copper, and Ethernet over fiber. If you want to create a private "Internet" between your own devices, MPLS networks are the same. DSL, cable, cellular and other broadband services that are popular with consumers generally fall into the "best effort" category. Only best efforts. Operators will do their best to get it up and running, but there's no guarantee what will happen.
Repetition is required
Even the best technology can break down. Amplifiers cut, back hoses cut fiber and copper wires with alarming regularity, and technicians make mistakes, taking your circuit offline more than you think. Accidents happen, but that doesn't mean your business has to be a victim.
One sure way to protect yourself from computer failure is to have a backup. If one fiber optic line is good, two are better... with some caveats. Repeat lines must be completely neutral. Ideally, you'll want to get them from different vendors who run different cable bundles in different directions out of their facility.
I remember a few years ago we had one of those trunk disasters at our cable company. Television and broadband repairs took two days, as more than 100 fiber strands had to be cut to complete the repair. You can hire ten of these strings to weaken your relationship and lose it to a big guy.
Can cable support fiber?
Business cable broadband can be a great way to get your connections back on track without doubling your budget. Cable services have become more reliable since the shift from large coaxial cable lines to fiber optic lines to a stud or neighborhood.
The now almost universal DOCSIS 3 standard offers hundreds of Mbps of bandwidth, even up to 1 Gbps in some areas. The cost per Mbps is a fraction of what you'd pay for Ethernet over fiber or legacy SONET. This is because cable service is truly a "best effort", bandwidth is shared, not allocated, and bandwidth is asymmetric. Mean download speed is much higher than upload speed.
With all this in mind, you can sleep better at night knowing that if your particular premium fiber is affected, you can continue uninterrupted with cable broadband unrelated to your primary service. You just need a way to ensure automatic failover so your employees and customers don't experience service interruptions.
Other options
Some companies are more than happy to have T1 channels, Ethernet over copper, two-way satellite, or 4G LTE wireless service as a backup to their main line. Any completely independent channel is a good backup candidate. The only real limits to all of this are the amount of bandwidth available and low enough latency that it won't affect broadband connection users.
Do you think that a single high-capacity channel makes you vulnerable to service interruptions? Why not consider an affordable broadband backup service for your peace of mind?
