Hello INNOG,

I'm sending you some quick findings about the speed throttling on my BSNL and Microscan fiber connections.

I have 300 and 200 mbps plans from them respectively, but if I try to download a file, say from a linux mirror, using a single connection "thread" like with using wget command, the speed I get is very low... 80 mbps or less, usually even 20-30 mbps for BOTH ISPs and both have Tata as upstream I believe.

They might just be throttling to their transit (or even to anywhere!) instead of the Tata upstream doing it.

I just now tried downloading a file from ubuntu india mirror (piconet webwerks) hosted in DE-CIX and also ESTO internet and both are exhibiting the slow downloads! Few days ago it was fast for local/indian mirrors and slow just for international locations.

The file I am downloading is the same hosted on their 2 networks:

https://mirrors.piconets.webwerks.in/ubuntu-mirror/ubuntu/pool/main/f/firefox/firefox-dbg_66.0.3%2Bbuild1-0ubuntu0.14.04.1_amd64.deb

and

http://ubuntu-archive.mirrors.estointernet.in/ubuntu/pool/main/f/firefox/firefox-dbg_66.0.3%2Bbuild1-0ubuntu0.14.04.1_amd64.deb

Same low speed observed if I try the file off international mirrors like:

http://se.archive.ubuntu.com/ubuntu/pool... (sweden)

http://us.archive.ubuntu.com/ubuntu/pool... (usa)

I am pasting the traceroutes from both my BSNL and Microscan connections to the piconet india mirror and the sweden mirror just FYI.

If you need some specific info from me, let me know, I will send what I can to you...

Let me know if there is some specific info you need that I missed out?

The reason why I am sending this email is to ask what may be the reason for low speed and whether it is intentional and can be improved?

Regards,

Vishal Rao
