One day in March of 2000, six of Google’s best engineers gathered in a makeshift war room. The company was in the midst of an unprecedented emergency. In October, its core systems, which crawled the Web to build an “index” of it, had stopped working. Although users could still type in queries at google.com, the results they received were five months out of date. More was at stake than the engineers realized. Google’s co-founders, Larry Page and Sergey Brin, were negotiating a deal to power a search engine for Yahoo, and they’d promised to deliver an index ten times bigger than the one they had at the time—one capable of keeping up with the World Wide Web, which had doubled in size the previous year. If they failed, google.com would remain a time capsule, the Yahoo deal would likely collapse, and the company would risk burning through its funding into oblivion.
