I have observed that in last 1 month or so Airtel has touched a new low.After throttling the download speeds for downloads from torrents, Airtel has now moved to limiting the download speeds for MS Windows and Office updates. Now download speed for MS updates is 70-80 kbps on a 4 mbps connection. This is not a problem related to slow downloads from Microsoft servers because download of updates using MTNL connection works without any problem.I have a PC with Windows XP and Office 7 on since last 5 hours and download of Office SP3 file of 275 MB is yet to complete.I guess Airtel believes that downloading updates on a PC and keeping it secure is a wastage of bandwidth that I have already paid for.Shame on Airtel for such low-life business practices.
