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.

Redundant Business Internet Connection Using Cable Broadband

Larger businesses have shunned what they consider to be “consumer” grade broadband services out of concern about availability and performance issues. While it is smart to deploy your mission critical business processes over dedicated circuits with service level agreements, you may be missing out on a very cost effective solution to backup your telecom services and improve access speed for Internet usage.

Cable broadband has experienced a rapid deployment and continued technical development largely due to its popularity as a consumer Internet service. Other options, such as satellite, wireless, dial-up, and fiber optic are either bandwidth limited, costly to install or often unavailable. DSL is a worthy competitor, but sometimes not located nearby.

What DSL and Cable have in common is that they give you a lot of bandwidth for a small price by telecom service standards. The 75 ohm coaxial cable has far more high end capacity than the unshielded twisted pair copper telephone wires used for DSL. Both offer great deals for 10 or 20 Mbps, but Cable is pulling away with DOCSIS 3.0 modems providing 50 or 100 Mbps now and capable of even higher speeds.

Today’s reality is that you can get 100 Mbps Cable broadband for about the same money as 1.5 Mbps T1 line service or 3.0 Mbps Ethernet over Copper. If you suspect there’s a catch, you’re right. The low price of Cable services are a result of sharing the network and the bandwidth with a large number of other users, mostly consumers. That advertised 50 or 100 Mbps goes up and down all day, depending on what your fellow users on the Cable are doing. If they are all casually browsing the Web, you likely have more speed at your disposal than you know what to do with. But when they start downloading movies and large software packages, there’s not so much excess bandwidth left to divvy up.

You don’t see these performance variations with dedicated line services. The term “dedicated” means you get exclusive use of all the bandwidth that line can carry. It’s less speed, but it doesn’t vary. When you aren’t running the line to capacity, the excess goes unused.

The other difference between Cable broadband and Ethernet or T-Carrier services is the service level agreement, also known as an SLA. These documents spell out commitments by the service providers in regard to service availability, performance characteristics such as latency and jitter, and remedies in case something goes wrong. If the line goes down, it is rare for it not to be repaired in a matter of hours.

Cable and DSL are considered “best effort” information services, which is another way of saying there are no guarantees or even promises. Even so, these providers have gotten pretty sophisticated as network operators and make every effort to keep their systems up and running.

The reality is that Cable broadband services can be great in the role of broadband backup. Consider that adding a second T1 line will cost you just as much and may not provide much additional reliability. T1 lines all come in through the same wire bundle and probably go to the same telephone company central office. Yes, if one pair breaks or is cut, you have the other line. But if someone with a backhoe chops through the entire bundle, both T1 lines go out. Cable has no relationship to either telephone wiring or the telephone company offices. True, there’s the possibility that some truck could run into the one pole that carries both the telephone and cable wires and knock out both. But for most of the run, your T1 line and your cable line go their separate ways.

The other thing to consider is that Cable’s high bandwidth may more than offset the variations you experience. You might not be getting 100 Mbps every minute, but you’ll likely not be dipping below 15 Mbps and even that’s 10x the speed of your T1 line. Users browsing the Web, sending email or download PDF files may be unaware of line variations. Data backups to hosted storage services will also benefit more from the higher average line speed than be affected by bandwidth variations, although upload speeds are significantly lower than download speeds on these asymmetrical services.

Are you concerned that you can afford only a single line service that could go down and leave you out of business for who knows how long? Why not protect your interests with Business Cable Broadband Service at a very affordable price?
