Here in Himaytnagar, Hyderabad it is pretty reliable It hardly goes down, only once I had a downtime for around 3-5 hours. Here the DSL light might go out for for a minute or two every 3-4 days do not know why It happens every couple of days may be they keep doing some stuff in their DSLAM frequenty but I do not have to complaints yet for downtime, actually reliance is one of the oldest pvt ISP provider in our building and the distribution box is in our building may be that is the reason.
