I have been using MTNL Broadband for some years. Recently I took their 320 kbps (Rs.495) plan. In July they started a midnight module between 10 and 8 with 512 kbps speed - download speed was between 68 and 72. I got this speed for one week, then I noticed that on Sunday nights the speed was the same as day time. Then I started experiencing this same problem on Saturday's also. Now, between Monday and Friday, I get a download speed between 52 and 58 kbps and on Saturday and Sunday, it is a extension of day time speed which is 320 kbps or between 38 and 42 kbps.I think the reduction of speed is an example of MTNL Broadband's Fair Usage Policy. While other broadband companies are upfront on advertising about their Fair Usage Policy, MTNL Broadband advertises they don't have one and then reduces the speed on certain days.
