By 2000, computers in classrooms had become common, although the size of the units would shrink considerably by the end of the decade. The college’s reliance on computers was most noticeable during blackouts. On January 29, 2003, a truck knocked down a transformer at the intersection of Lemon and Commonwealth Avenues, shutting down power for blocks around the campus. Classes were let out early. An equipment failure on Lemon Avenue on September 15, 2009 led to another massive power outage on campus.
