I suggest no "Bandwidth Hugger" should give up their Airtel connection right now.
This is what they want and you'll be playing right into their hands.
They want to get rid of the leechers and get more of the innocuous emailing orkutting surfer.
The best thing will be to make sure all your downloads are queued between 8 am to 4 pm.
Better yet, download a linux distro or schedule your automatic updates to 11:00 am - 12:30 pm and 2:30 pm - 4:00pm
And each of us should take an oath never to recommend an Airtel "Broadband" connection or any of their telecom services in a public forum.
