One of India’s top engineering schools has restricted Internet access in its boarding houses, saying addiction to surfing, gaming and blogging was affecting students’ performance, making them lonely and even suicidal.

Authorities at the best Indian Institute of Technology (IIT) in Mumbai said students had stopped socializing and many were late for morning classes or slept through them. “Now, a student doesn’t even know who lives two doors away from him because he is so busy on the Internet,” said Prakash Gopalan, dean of Student Affairs. “The old dormitory culture of companionship and socializing among students is gone. This is not healthy in our opinion.”

IIT­Mumbai, with about 5,000 students, is one of the seven IITs across India which are considered to be among the finest engineering schools in the world. They are also a talent pool for global technology giants. But their hard courses, tough competition and lonely campus lifestyle have taken an effect on students. Depressive and dysfunctional lifestyles are known to be common among IIT students, and at least nine have committed suicide in the past five years. Students have unlimited free Internet access in their boarding houses to help them in their studies, but many also use it to surf, chat, download movies and music, blog and for gaming.

“Starting Monday, Internet access will be banned between 11 p.m. and 12:30 p.m. at IIT­Mumbai’s 13 boarding buildings to encourage students to sleep early and to try and force them out of their shells.” Gopalan said. But the move has not gone down well with students who say they hate their lives being regulated. “Now they will say we need to listen to a lullaby (摇篮曲) to go to sleep.” said Rajiv, an electronics student.
