I was upgraded to 1Mbps on the 1st of month like many other BSNL customers. I crossed my FUP on first day itself. My speed was revoked to 512Kbps afterwards. Later, I went out of town for about week and when I returned today my speed is back to 1 to 1.5 Mbps !!! I am not getting constant 1Mbps but its spiking to 1.5 Mbps and back to 1 Mbps but never less than that. IDM shows download rate of about 150KB/s.Anyone else having similar treat ?? !! I am from Pune.
