I have a similar issue - very slow download - with my ADSL access provided by SFR in France. I did similar tests, by downloading the same file from servers hosted at different providers, and the bandwidth was always very slow, except when I changed the HTTP port from 80 (the standard) to an arbitrary chosen number! This change alone made me able to use the full bandwidth provided by my physical link! It was the proof that my ISP was running some kind of traffic shaping, which is a shame.

No such issue over here (SFR FTTH), bandwidth is extremely stable and through the roof. Free SAS is absolutely terrible in that regard. I ran a few experiments (at home - when I was still a customer - and at friends') over the years similar to that blog post, and starting 17:00 things get throttled down to death due to clogged pipes. It's almost on the clock. The behaviour is immediately obvious to anyone having some background in network engineering, and support is tone deaf to the issue.

  Same conclusion from me. Free will throttle everything from 17:00 to 00:00 and during the week ends these last few weeks. On the other hand I don't know any other provider who just gives a fixed IP.

    Same story with Free ADSL: I used to get terrible speeds from anything on AWS (including our own services), around 100 KB/s, until very recently when suddenly I was able to saturate my ADSL line from them. Now I don't dread having to download GB-sized log files. It didn't really make sense to me why AWS was a target of their bandwidth extortion tactics until I realized Netflix uses AWS.. So I guess thank you Netflix for paying the ransom?

    > On the other hand I don't know any other provider who just gives a fixed IP. SFR does (at least on FTTH) and you also get native IPv6 (not 6rd) and (IIRC) a /48. That is, unless you're subscribed via RED (which I currently am) in which case the IPv6 feature is disabled on the remote end (you can enable it on the NB6 router but it just sits there waiting for the prefix to be announced). On cable the router is different but they're on DOCSIS 3.0 mostly by now and I hear at least some people do get IPv6. Orange still leases dynamic IPv4, dunno if they enable IPv6 by default now or if it's getting tiered like SFR.

  I'm not surprised it works flawlessly with SFR FTTH. The traffic shaping I noticed only happens in the areas where SFR outsources the ADSL termination to Axione, which is the case where I live (near La Rochelle).
