How long can the company tolerate downtime If your company does require Internet connectivity, how long can the company do without it Five sec onds Five minutes Five hours This is an important question that must be addressed and brought to the table with management. Do not wait until connec tivity is unavailable before posing the question to management; it might be too late. Wall Street companies that trade stocks using the Internet might be allowed 1.5 seconds of downtime, whereas a company selling flowers might be able to lose its connectivity for several hours and incur little or no financial loss. What is the cost to the company if downtime occurs It is very important that you can quantify the cost associated with lost Internet connectivity. That is, how much would the company lose for each minute remote users or company employees couldn t connect to the Internet This can be very difficult to quantify, especially if the company is not selling services using the Internet. If you are using the Internet to sell services, you should be able to get at least a daily average of the company s earning from Internet sales. Of course, the revenue earned might not be from immediate sales, but from future revenue earned from the company s Internet presence. Will downtime cause a loss of customers It definitely can. For example, a company s absence from the Internet for several days can prompt potential clients to remove that company from their Favorites Web page. Most Internet shoppers move on to a new site when they have to wait more than several seconds for a Web page to display. Having to wait several minutes, or even hours, could prove disastrous. What internal network services, if any, rely on the Internet connection For example, do remote users access internal resources across a VPN If it becomes unavailable, this can essentially prevent employees from doing their jobs. What is the associated cost if there is no redundant system Calculating the hourly wage of each remote employee, including the benefit package costs (health, vacation, sick leave, and so on), shows that lost wages can be considerable. It can be more difficult to quantify the possible loss of sales due to the inabil ity of a sales representative to close a sale because of the downtime. In any event, you must attempt to get as accurate an assessment as possible to help you determine if adding an additional Internet connection is financially prudent. Which connections already offer redundancy If remote users are connect ing to your company s resources using the Internet that is, by a virtual private network (VPN) is there any other means of connection if the Internet becomes unavailable (VPNs are covered in detail in 10, Designing a Remote Access Strategy. ) A VPN uses the Internet as its medium to send and receive data throughout your company s network infrastructure. The question here is, if there were no contingencies in place, and the ISP ceased to provide that connectivity,

would there be another way to get to that data Or, if the company leased a Frame Relay connection, would there be a redundant link if that Frame Relay link became unavailable In many cases, employees can go home and access the Internet from there. And don t forget, if e-mail is down, a telephone can still be used.

Many companies rely on their ISP to provide the means of connectivity for all their users. In fact, the ISP, for many small companies, is the only infrastructure in place that enables users and customers to access the company s resources. Virtual private networks (VPNs) are a cost-effective method of making network resources available for outsiders and insiders alike, but there is a hidden cost associated with it: fear of the unknown. Relying on the uptime of an ISP for sales and electronic communications can be a high risk for any company. At one time, Internet service providers popped up all over the country as quickly as dotcoms. Some disappeared just as quickly as they appeared. This means that you must do your homework when you design your Internet connec tivity and put your company s reliance on a particular ISP strategy. Before selecting an ISP for the implementation of your VPN or connectivity to the Internet, consider the following:

How is the ISP connected to its peers Does the vendor offer your company any guarantees or service-level agreements For example, do they guarantee 99 percent uptime How do they measure this uptime What is the penalty if they don t meet their guaranteed uptime Does your ISP offer any security features, such as intrusion-detection systems, or firewalls For example, some ISPs offer only VPNs using Point-to-Point Tunneling Protocol (PPTP) with a lower level of encryption, whereas another might offer Layer 2 Tunneling Protocol (L2TP) with Internet protocol security (IPSec) protection. How does the ISP or vendor handling your network connectivity monitor your usage Are you given reports showing the daily usage or weekly usage of bandwidth or network resources Is more than one vendor involved in the connection to the Internet For example, is one vendor responsible for the physical link (T-1 link) and an ISP responsible for connecting to the Internet If so, how do the companies get along If there are inherent problems between the two companies, your company might well be affected. In some cities, companies are responsible for both the hardware and cabling infrastructure as well as connectivity to the Internet.
