Thanks for the response (and to others too). In retrospect my point wasnt clearly made. I think somw have understoof but not others. To spell it out further - My concern is google effectively becoming essential internet infrastructure here - the only reason i see for them to support such a process is a view that they can charge a for profit service for the same in the future (though may still remain free to some). In the past the internet has been a free, open, equitable and low cost platform. Googles interest as a commercial company is not to stop ddos altogether but to commodotise and profit from it. Is that the internet we are heading towards? Are there better alternatives?
