TRAI buckled under before the DDOS
I was attempting to view the web pages containing the comments from "others" - the internet users of India - and was able to browse and download a few days worth of comments till about 2pm IST, when some of the pages 404'ed.
I suspect TRAI had at that time started the process of removing the pages, in response to reports in the media blaming TRAI for the loss of privacy of Indian netizens. The DDOS started a little later, I think; TRAI had already buckled in and was attempting to remove the pages containing email addresses and other personally identifiable information about Indian internet users.
