Summary

  • The University of Malawi’s Fidonet node logged telephone calls and messages, then used its records and phone bills to calculate monthly and cumulative cost per kilobyte of international mail.
  • The measurements describe one store-and-forward system and its telephone links. They are not an audit of Malawi’s telephone network, a full Internet connection, or a count of national Internet users.

Analysis

A network built around the bill

In 1992, Paulos Nyirenda proposed a modest experiment: could computers and ordinary telephone lines improve communication among the University of Malawi’s distant colleges and research institutions, and how would that cost compare with travel, fax and voice calls? The first budget was 5,123 kwacha, which he described as roughly US$1,000. The project was not a miniature Internet backbone. Its starting point was a practical problem: information moved slowly between institutions spread across the country, while calls were expensive and line quality poor.

A direct line reached Chancellor College in Zomba in September 1993. The node ran Fidonet software on a borrowed 386 computer with a 2,400-baud modem. It prepared messages and files offline, compressed them, and sent them when a telephone connection was available. Users could reach the campus network with a local call; international messages waited at the node for a scheduled connection outward.

The first international arrangement was awkward. Malawi’s Fidonet address sat under the University of Zambia network, but connecting to that node was difficult and the line quality poor. In November 1993, Nyirenda’s team switched to the Africa Zone Gate at Rhodes University in South Africa. He reported that connection success and quality improved. That is an operator’s account of one route, not a measurement of every line in Malawi.

The node then made its own operation legible. Its software produced daily, call-by-call and message-by-message logs. A tracker recorded message origin, destination, date and volume. The team also collected telephone-billing data and built tools to analyze the logs. The published performance series covers October 1993 through March 1994 and focuses on international mail volume.

Nyirenda calculated phone-network cost per kilobyte by comparing the telephone bill with the volume carried. On a monthly basis, the reported figure fell from MK 4.68 per kilobyte in October to MK 0.88 in March. The cumulative calculation moved from MK 4.68 to MK 1.10. Those are the chapter’s figures for this node and measurement window. They are not the cost of every network function, the price of Internet transit, or an independently audited national tariff.

The records served a second purpose: they made cost recovery discussable. The node recommended a charge of MK 1 per kilobyte of international mail sent or received. Nyirenda said the rate was still in place when he wrote in 1996. Users, he reported, preferred message-by-message billing to a flat fee. This was a service design grounded in metered traffic, not a claim that every organization had the same ability to pay.

The contrast with full Internet access matters. In May 1995, Nyirenda told the Network Startup Resource Center that the Fidonet network had more than 120 computers or organizations linked and about 600 users, while a full Internet service still depended on finding funds. In May 1996, he said the system remained mainly store-and-forward and full-IP funding had not yet been released. A 1997 traceroute to a MalawiNet server later showed a path from the United Kingdom over an E1 satellite link. It is a useful boundary marker, not proof of public access everywhere.

The surprising output of this early network was therefore not only email. A service designed to move messages cheaply also created operational evidence: which calls completed, how much international mail moved, and how the phone bill compared with that volume. The evidence could guide the node’s own design and billing. It did not establish that the telephone company changed its service or that the whole country had become connected.
