You seem to have misunderstood. I did not mean the availability of speeds. I meant the definition as per TRAI. As per what I checked just now, TRAI's definition of "broadband" in India has been updated to 512kbps since Jan-2011.

According to Google, the page here http://www.trai.gov.in/broadbandpolicy.asp was updated/cached last in 2006 so maybe thats why it still says 256kbps
