Because, in the world’s fifth-largest country by land mass, being on time to a party is uncool and uncouth. “The unspoken rule is that the host waits until the time the party is supposed to start, and only then begins to think about having a shower,” a translator explained in a BBC travel piece. ARPANET, one of the earliest computer networks, arrived in Brazil hora inglesa, in 1975.<br>Less than two years after ARPANET’s first international connections, Vint Cerf and Keith Uncapher demoed a connection to the network from São Paulo at the first Latin American Seminar on Data Communication. The party had officially started. But Brazil had every intention of being fashionably late.<br>It was a three-ring circus, orchestrating the South American country’s introduction to Western networks. The Brazilian government wanted to control the flow of information across borders, while academia championed unfettered access to international research, both of which were hampered by local telecoms that coveted monetization.<br>In the end, all it took to break the impasse was a few copper wires, laid across the Gulf of Mexico to a high-energy physics lab just outside of Chicago, in 1991.<br>The whole internet in your inbox<br>Email and messaging were, for both academics and hobbyists, the biggest motivation to connect to Western networks. “The physicists, for example, did their master’s and PhDs abroad, and wanted to maintain contact with researchers in other countries,” Brazilian Internet Hall of Fame inductee Demi Getschko remembers. “Outside Brazil, e-mail was already being used extensively, but we didn’t yet have it in Brazil. So then we began to research how to bring it here.”

B1726 machine via Classic Computer Brochures<br>Getschko, for his part, worked nights at the State of São Paulo Research Foundation (FAPESP), programming software to manage the foundation’s grants and research. Computer hardware was expensive, even before factoring in Brazil’s import restrictions. So, Getschko and his boss operated out of a house, alternating shifts to get the most out of their Burroughs 1726 machine.<br>“I would work there at night. I began going to the house on Pirajussara Street three times a week, turned on the Burroughs and tried to write some of the programs.” During one of his shifts, Getschko met Oscar Sala, one of the physicists who pined for email after studying in America. Sala was a FAPESP board member and friend of Fermilab.<br>As interest in networking grew both domestically and internationally, FAPESP moved its headquarters to a bigger building. “I still remember the day in which we moved the equipment from Pirajussara Street to the new headquarters. The B1726 was transported in a half-open truck. I went with it and prayed for it to not rain.” It would be several years before Getschko got the country connected to the internet, but the pace of...
