The first time I ever heard the words “mirror website,” I was sitting at a debris-strewn desk, hunched over a desktop computer, on the second floor of a nondescript office building on East 29th in Manhattan. I’d recently started volunteering with the New York City Independent Media Center, an organization that would turn out to be one of the first “citizen journalism” organizations in the United States — though certainly no one would have called it that at the time. The IMCwas in its third day of participant-powered coverage of protest actions taken against World Economic Forum (WEF) meetings in New York. It was less than five months after September 11; the city was cold and bleak, and people were tense. Really tense. And our website, NYC Indymedia, had slowed to a crawl.

“It’s going to crash,” I muttered.

“Don’t worry,” I was told. “We’ve got it mirrored on a bunch of backup servers. The updates from people using the Open Newswire won’t show up right away, but they will show up, and people will still be able to read the site.”
