This is the On-line companion to my monthly column in

The National Publication for BPR
Finding the Ideal Internet Provider
(From the October 1996 issue)
Throughout the year, I have provided pointers to many valuable Internet
resources. Implicit in my advice was the assumption that you all had fast,
reliable access to the Internet. This column is dedicated to those of you
who are shopping for a new/better Internet service provider (ISP).
Dial-up Connection
A dial-up connection is suitable for individuals users, or workstations
that are not on a corporate network. With this style of connection, you use
a modem and existing phone lines to reach an ISP. There are thousands of
Internet Service Providers who provide access to individual users and
companies. The most complete list of providers is located at The List. The
List is useful in that you can search for an ISP based on country, state,
or area code.
The List may indicate several dozen ISP's who serve your area code. The
List may also provide summary information about the ISP and a link to that
ISP's home page. There are several considerations for picking an ISP for
dial-up services:
* ISP's are accessible via their points of presence or POPs. What is the
phone number of their nearest POP? This is the number your modem will
repeatedly dial (for potentially long periods of time). Once you find
out the phone number of their nearest POP's, you call your local phone
company and determine if calls to that number are within your local
unlimited calling area. The cost of "non-local" phone calls will
easily surpass the slight differences among the ISP's monthly fees.
* How is the ISP interconnected with the rest of the Internet? They
should have at least a T-1 connection from one of the major backbone
providers (discussed below)
* Are there busy signals? Pick up your phone and dial their POP phone
number several times a day during the times when you hope to get
online. A low monthly fee means nothing if you can't get through.
* Do they offer additional services that you need such as web hosting.
Many ISP's may include a portion of disk space on their web site for
you to store web pages. In this case, your web address will look like
http://www.ISPname.com/yourname. A webspace of your own (i.e.
http://www.yourname.com) may also be available, but this will cost
additional money.
* Finally, you can consider price. In the Washington Metro area, we are
fortunate that monthly rates range from $15-$35 per month for
unlimited access time and a few megabytes web storage space. I would
avoid pre-paying for a year's worth of service until you've used the
service for a while.
Dedicated Connection:
Organizations with a significant number of users on a LAN will be interested
in a dedicated connection. A popular size connection is a "T1" which
provides up to 1.5 Mb/sec of throughput. ISP's charge a flat monthly rate
for a T-1 which includes their fee and the cost of a dedicated line from
your location to their nearest POP. The ISP will arrange for the dedicated
line usually through the local phone carrier.
When shopping for a dedicated connection, I would recommend that you only
consider those ISP's who have significant backbone capacities and who are
directly connected to the Internet's Network Access Points, or NAPs. Out of
the many thousands of ISP's, there are only a handful which operate
extensive high-speed backbone networks. Most other ISP's derive their
connectivity from the larger ISP's. Russ Haynal's ISP Meta Site lists
several of these major ISP's and includes linkages to the major US NAPs,
complete with lists of who is connected at each NAP. Examining the list of
ISP's connected at each NAP, will help indicate which ISP's are the major
providers. You may also want to consult Jack Rickard's informative article
about the Internet's architecture.
In comparing the top half-dozen ISP's, you will want to examine their
backbone network. Buying a T1 from an ISP is worthless, if they don't have
the capacity to handle the aggregate traffic of all their users. A good
example of a backbone is UUNET's backbone map, where you can see redundant
T3 (45Mb/sec) connections into many major cities. I would not buy a
dedicated Internet connection from an ISP who won't show you their backbone
diagram. You will also want to understand how your connection enters into
their backbone, and how your traffic will ultimately reach a NAP. If your
existing corporate connection seems slow, ask your ISP about these backbone
details.
Some ISP's will also offer a variety of services which you may need.
* Router configuration for your dedicated connection
* Firewall products for enhanced security
* Web hosting services
As with most service industries, there can be a wide variety in the quality
of service provided by these ISP's. Many ISP's are growing exponentially,
and may not have the financial resources to "grow gracefully" Be sure to
ask around. Many people love to tell you want they think of their ISP ;-)
Note: I recognize that even this column assumes that you have access to the
Internet. If don't yet have access, your options include:
* Take one of those free AOL disks, open a trial account, and use it to
shop for an ISP
* Borrow some online time from friends, library, or cyber-cafe
* Look through the business section of the newspaper
