I agree, even BSNL what i have is also through local LCO only. I also have forgot what internet downtime is. It depends on LCO not related to network.Airtel entered in my area through LCO partnership. But airtel have much strict control over LCO unlike local ISP. My LCO also provides connection of GTPL, Alliance Broadband, BSNL, Railwire, Wishnet. But airtel service is the best. In last 7 months I've forgot what internet downtime is.
