My brother used to be a student of NIT Puducherry. According to him, the internet speed easily reaches the top of 40 Mbps to 50 Mbps, which is by far the best service provided to students. Other than that, the LAN connections are to be mounted very soon at the institute body so as to help enhance the connectivity speed over time.
The wifi speed once recorded reached almost around 1.1 Gbps in the laboratory, which is the maximum my brother and his friends witnessed.
