An excerpt from the article After Hours - Campus Life from Dusk to Dawn, by Graham F. Scott in the University of Toronto Magazine, Spring 2006 Issue.
In the deepest reaches of the McLennan Physics Building on St. George Street is a room that’s crucially important to every student, and staff and faculty member – though few have ever seen it. Stored in this heavily air-conditioned bunker are the e-mail servers, payroll mainframes, Cray supercomputers and hundreds of other blinking, whirring and buzzing computers.
Network Operations (as it’s called) is like Grand Central Station, and it’s Sam Harrichand’s job as a shift supervisor to keep the trains running.
“See that red light?” asks Harrichand, pointing to a blip on one of the five monitors that indicate network traffic. “That’s someone launching an attack.” The hacker, location unknown, can’t find a chink in U of T’s armour. But other hacks have broken through.
“If the network goes down or the mail servers fail, I have to wake people up in the middle of the night to fix it,” he says. While such hacker attacks present a serious inconvenience, Harrichand says they make his job interesting. “I have to act quickly to get the network back in working order,” he says.
Harrichand blocks about a dozen attacks during a 12-hour shift, but the threats are mostly minor. “I like the work,” he says. “It’s quiet.”
