I think your line is absolutely not the problem here, I think it's BSNL's backend/interconnecting links/upstream/etc - this has been discussed in some other threads such as
https://broadband.forum/bsnl-broadband/76312-bsnl-broadband-routing-issue-high/ (check page 3 - there are live updates of BSNL's gateway performance as seen from Mumbai)
These are the IP addresses for all of the speedtest.net servers in India: maybe you could try a traceroute to the following IPs:
182.19.95.36 - Mumbai (Vodafone AS55410)
182.19.95.104 - Delhi (Vodafone AS55410)
202.134.194.5 - Delhi (Hughes AS17648)
223.224.40.114 - Delhi (Airtel AS9498)
182.19.95.68 - Chennai (Vodafone AS55410)
202.148.202.180 - Chennai (Aircel/Dishnet AS10201)
223.224.43.250 - Chennai (Airtel AS9498)
223.224.50.242 - Hyderabad (Airtel AS9498)
223.224.49.254 - Bangalore (Airtel AS9498)
223.224.58.29 - Kolkata (Airtel AS9498)
118.102.198.56 - Kochi (Aride Ocean/Aircel/Dishnet AS10201)
Yes i understand, was active in that thread.
The speed today has been on the downside, coming down below 1.5 Mbps
