Errrmm... From Bangalore to Gurgaon & Ghaziabad, airtel has been terrible for gaming. The packet losses terrible despite getting rewiring done but then we didn't have OFC but in Bangalore despite OFC it hasn't been great either.
You broadband was decent in Gurgaon when we switched from airtel but even they were lousy as hell. It can be gauged by the fact that they didn't have a UPS at their node near our society so whenever there was a power outage, there won't be internet. In Gurgaon it can easily last over an hour. This connection was on for more than 18 months but they couldn't provide UPS !
