In a tribute to Aaron Swartz, the 26-year-old cyber activist who committed suicide earlier this month, computer hackers took down the website of the Massachusetts Institute of Technology for an hour on Tuesday.

Outside viewers who visited the university’s web domain between 11:58 a.m. and 1:05 p.m. saw a black page with white text reading, “R.I.P. Aaron Swartz, Hacked by grand wizard of Lulzsec, Sabu.” The student newspaper, The Tech, reported the outage -- at least the second time in the last month that MIT has been hacked.
