Backing Up Broadband

By: John Shepler

In the last couple of decades, broadband Internet access has gone from being a marginally used business tool to a critical infrastructure for most companies. Both speeds and traffic have increased by orders of magnitude. So, answer this question: “what happens if your broadband goes down?”

We’ve Quietly Become Dependent
The conversion from traditional to automated business processes and digital communications have taken place so gradually that many companies don’t quite realize what would happen if it all suddenly went dead. You know what happens if you lose power. That facility is temporarily out of business. You know what happens if your data center loses power. Your computer-based processes are out of business. If that’s not acceptable, then what have you done to ensure continuing operations?

The Danger of Single Point Failures
What is the communications equivalent of battery and diesel generator backup for electrical power? It’s one or more redundant communications paths. If you have a single broadband line powering your network, you have what’s known as a “single point failure”. That’s one place where a failure of any sort puts you out of business. You can have all sorts of extra computers, printers, servers, battery backup and people cross-trained to take over whatever is a priority task regardless of who gets sick. It’s all for naught if yours is an online business and there is no way you and your customers can connect.

Start With the Best Line You Can Get
There are broadband services and then there are broadband services. They really break down into two categories. There are telecom services designed for high reliability and often available with service level agreements, a type of performance guarantee. Then there are “best effort” services designed for low cost and no performance guarantees. Which do you suppose is best for your critical operations?

Telecom based services, such as T1, DS3, SONET, Ethernet over Copper and Ethernet over Fiber are examples of dedicated high reliability services. So are MPLS networks if you want to create a private “Intranet” among your own facilities. DSL, Cable, Cellular and other broadband services popular with consumers generally fall into the “best effort” category. Best effort means just that. The carrier will make their best effort to keep you up and running, but there is no guarantee of what that will wind up being.

The Need For Redundancy
Even the best technology can go awry. Amplifiers short out, backhoes cut through copper and fiber cables with alarming regularity, and technicians make mistakes, perhaps disconnecting your circuit instead of the one they intended. Accidents will, indeed, happen, but that doesn’t mean your business has to be the victim.

One tried and true way to protect yourself from equipment failure is to have a backup in place. If one fiber optic line is good, two are better… with some caveats. Redundant lines really need to be independent. Ideally, you want to get them from different carriers who run them in different cable bundles that even leave your facility in different directions.

I remember a few years ago when our Cable company had one of those backhoe mishaps. It took two days to get TV and broadband restored because they had to splice over 100 fiber strands to complete the repair. You could have leased ten of those strands to make your connection redundant and you would have lost everything in one big chop.

Can Cable Backup Fiber?
Business cable broadband can actually be a very good way to get redundancy into your communications without doubling the budget. Cable services have gotten a lot more reliable since they switched from large coaxial trunks to fiber optic runs to the curb or neighborhood.

The DOCSIS 3 standard, that is now almost universal, offers bandwidth capability in the hundreds of Mbps, even up to 1 Gbps in some locations. The cost per Mbps is just a fraction of what you’d pay for Ethernet over Fiber or legacy SONET. That’s because cable service is, indeed, “best effort”, the bandwidth is shared, not dedicated, and the bandwidth is asymmetrical. That is, download speeds are much higher than upload speeds.

Taking all that into account, you may sleep a lot better at night knowing that if your premium dedicated fiber takes a hit, you can continue operations uninterrupted with broadband cable that is unrelated to your main service. You simply need a way to ensure automatic failover so that your employees and customers won’t see a service interruption.

Other Options
Some companies are quite happy to have T1 lines, Ethernet over Copper, two-way satellite, or even 4G LTE wireless as backup services for their main channel. Any channel that is completely independent is a good backup candidate. The only real limitation to any of these is the amount of bandwidth available and latency low enough not to impact what you are doing with the broadband connection.

Are you feeling that a single high capacity line is leaving you vulnerable to a service interruption? Why not look into an affordable broadband backup service for peace of mind?

Internet Service Without The Outages

The Internet is an amazing place for finding out just about anything related to anything. The sum total of human knowledge is migrating online. Even old books and papers are being scanned and loaded onto webpages and data bases. Combine that with real-time access to shopping, financial services, music and video and you are pretty much attached to the Internet at the hip... or at least the brain. The one major aggravation of Internet everything is when you just can’t get to it.

Internet outages are almost always local events now. The network is so large and so robust that the entire Internet just doesn’t go down. It only seems that way. Perhaps it’s your favorite site or application that is temporarily offline. Perhaps you just can’t get to anything at all.

I’ve felt this pain to varying degrees over the years. As a night owl, I know that the wee hours are the time that network administrators target to do their maintenance. That means my ISP can go offline for an hour or two without warning. It also means that any given online service my be down for maintenance with little or no notice.

Then there are the unplanned and uncontrolled outages. Construction work is famous for taking down telecom services. It’s so prevalent it has a name. They call it “backhoe fade.” It’s pretty much what it sounds like. Someone with a backhoe digs in the wrong place and chops through a wire. A year or two ago, they chopped through a fiber optic cable. There were over 100 strands in that cable and my service was on one of the last to be fused back together. No Internet for two days.

Well, not exactly. The cable modem was dead for two days. I was getting things done at any restaurant where they had free WiFi that wasn’t affected. Inconvenient? Yes, but it got me through.

I’m tied to the Internet for my livelihood, but a local outage isn’t the kiss of death. It’s just a major inconvenience. The reason for this is that all of my hosting, dozens of domains worth, is done elsewhere. In fact, I insist on having multiple hosting services located in different data centers in different cities. That way a local disaster won’t take everything down at once. This happened about 8 years back. Remember the 4 hurricanes that hit Florida in 2004? One of them flooded the building my web host was in. Even though they were on a higher floor, the communications lines were affected so no data was going in or out.

This hints at the first thing you can do to protect your business from Internet outages. Don’t put all of your eggs or servers in one basket. You have more protection when the services you use are divvied out geographically. Disasters rarely affect more than a limited area. This is true for cloud services too. Your cloud provider needs to have diverse backup solutions or you need more than one cloud. Nowadays, that also means you need more than one way to get to the cloud.

Backhoe fade is a fact of Internet access, although there are more and less risky solutions. All in all, you are better off with dedicated Internet access that has an SLA or Service Level Agreement. The really cheap Internet services, DSL and Cable, are shared and not dedicated to you alone. They are also treated as “information services” not telecom services, meaning that the providers don’t jump nearly as high or as fast when something goes wrong. T1 lines, Ethernet over Copper, Ethernet over Fiber and SONET perform better, have faster mean times to repair and cost more... as you would expect.

It’s good to have diversity in your connectivity. Two T1 lines are better than one. Ethernet over Copper using multiple pairs is more reliable than anything coming in on a single pair. Even better is copper backup for fiber services, even thought it may be slower. There is no one cable that has both the copper wires and fiber strands in it. A cable broadband service can be an inexpensive backup service to your dedicated lines since it doesn’t use telco wiring. Wireless broadband is an excellent backup that also doesn’t have to be that costly. Your smartphone gives you a level of redundancy when your desktop PC goes down. There are fixed wireless services designed for business backup running on 3G and 4G cellular networks. You can set these up for automatic failover so that service won’t be interrupted if you lose a landline.

How much you need to concern yourself with redundancy and disaster recovery depends on what happens when you lose your connection to the Internet. Is it a minor inconvenience or does everything come to a screeching halt? If that’s the case, make sure you have at least two ways of connecting and getting your work done. They don’t have to be the same bandwidth or guaranteed availability. Just make sure that there is no single point of failure that will knock them both out at the same time. There are lots of different services available. Check prices and features so you can get the best mix of business bandwidth services available for your particular location.

TelePacific Takes Business Continuity Seriously

TelePacific Communications, a competitive telecommunications carrier serving customers in California and Nevada, is taking a comprehensive approach to disaster planning and the need for business continuity that follows disasters natural and man-made.

Their Business Continuity Services are focused on maintaining your ability to use voice and data services in the event you lose a trunk line or even your entire facility. But how just how can you do that?

Let’s take a look at telephone first. Most medium and large size businesses, and some smaller businesses that are heavy users of telephone communications, are using digital trunk lines. T1 PRI and SIP Trunks provide one to two dozen outside lines for management by an in-house PBX system. That trunk line offers a considerable cost savings over multiple individual phone lines, but does represent a single point failure risk. With that in mind, you can backup your primary trunk line with a few individual analog POTS (Plain Old Telephone Service) lines. The key is to have the phone system programmed to automatically switch over to the backup lines when the trunk goes down. Another approach offered by TelePacific is to have your incoming calls automatically forwarded to the backup lines.

Even smaller businesses using IP PBX systems or Analog Telephone Adaptors may keep one analog telephone line in service as an emergency backup. The idea is that a fault that takes out your digital data line may not affect the analog lines. In many cases, that’s true. But what happens if a construction accident cuts all the underground lines in an area or the ground opens up in an earthquake and breaks every wire in the area?

If all your telecom connections are out, you may have also lost power. In that case, TelePacific has the ability to forward your incoming calls to a number at another business location. You could also choose to have your most important numbers, such as your main phone line and FAX number, forward to a mobile phone or even a residence. If there are too many incoming calls for you to answer immediately, the overflow can be answered by voicemail at the carrier’s facility. You then have the option to listen to and return those calls from another location when time permits.

Data lines, such as Dedicated Internet Access, are subject to the same disasters that befall telephone lines. T1 lines are the most popular connections for business users. If all you have is a single T1 line and it goes down, your connection is broken until it is fixed. But bonded T1 lines can be set up so that if you lose one, the secondary or other T1 lines will keep running. Your bandwidth will be temporarily reduced, but you’ll still have broadband connectivity.

Of course, if all lines are cut you will lose data service coming in and going out of your business location. If you have a second business location you can set up a private IP VPN arrangement so that all traffic can be routed to the secondary location. If you have only a single facility or all of your offices are located so closely together that they might all lose power or communications in the same event, you probably want to think about using a colocation service. A carrier colocation facility is probably more robust than your onside data center. The facilities are built with extensive physical security, fire and flood control, and both battery and generator backup. They also have multiple incoming and outgoing trunk lines going in different geographical directions.

TelePacific offers colocation facilities as do other providers around the country. You can house your application servers there and have an email backup server in case your primary email server fails. Remote data storage is a necessity these days since the most important business documents are now electronic documents.

Do you feel a bit uncomfortable with your ability to conduct business in the event of a fire, flood, tornado, earthquake or other unforeseen disaster? If not, it’s worth your time and peace of mind to talk with an expert consultant who can recommend the most cost effective ways to ensure your business continuity.

Winter Of Our Disconnect

Now is the winter of our disconnect
Made reliable by redundant connections.

It's perhaps poor Shakespeare, but good business practice to be planning for what will happen when your communications lines go down.

Look at what happened this winter in the Mediterranean. Multiple undersea cables were mysteriously cut, causing a major disruption in Internet service to Egypt and India and slowdowns to many countries in Europe and Asia. The culprit could be as simple as a snagged boat anchor.

Telecom line breaks happen often enough that they have a name: "backhoe fade." A common reason that your voice and data circuits suddenly stop working is that someone digging with a backhoe punches right through a copper or fiber optic cable. Other times, a car or truck slides on the ice and knocks down a telephone pole. Or, an electronic repeater just gives up the ghost at an inopportune moment.

Not that service interruptions in any particular location are at all common for professional-grade telecommunications services such as T1, DS3 or Ethernet. But if being able to use the telephone or Internet are absolutely essential for your company, you might want to think about a way to ensure continuity of service. You can do that with redundant connections.

A simple form of redundancy is an analog fallback circuit for your enterprise VoIP telephone system. Many VoIP interface adapters and IP PBX systems offer a "lifeline" option that is simply a common analog telephone line. Normally you make and receive calls using your T1 PRI or SIP digital trunk line. But if you happen to lose that service, the system will automatically engage the analog line or lines. One or two line are probably sufficient to get you through the outage.

Other systems, especially for point to point and dedicated Internet data connections, employ routers with dual WAN inputs. Two T1 lines plug into the back of the router. The best setup is to be able to use the full bandwidth of both lines in normal operations and gracefully fallback to one line's worth of bandwidth if there is a break.

Now, there is a trick to making this work properly. For true redundancy, your line services have to be completely independent. That certainly means not having both lines in the same binder cable. Preferably, your services come from different vendors and are delivered to your company from different directions.

One low cost alternative for businesses that use DS3 or Ethernet over fiber optic cable is to have a backup T1 line in place. The bandwidth of a T1 line pales in comparison to the higher order services, but being copper-based you can make sure that it isn't bundled with the fiber optic cable. That can avoid common backhoe fade. Electronics failures in either connection won't affect the other's performance.

Wireless options can also offer redundancy for your wireline services. A cell phone will usually still be working when you have an electrical or communications failure in the office. Cellular broadband cards in notebook computers can provide broadband Internet access without the need for either power or telecom lines.

If you are interested in higher reliability communications, especially if you are currently using DSL or Cable broadband at business locations, let our expert consultants find you cost effective redundant communications options to make sure you will always be connected.
