Do other ISPs apply a more aggressive cap? I wonder if this is to manage bufferbloat?

It has absolutely nothing to do with bufferbloat and everything to do with ensuring the committed and burst speeds remain within OR specification so the whole thing doesn’t turn to [censored].

Remember this is a wholesale network that has dozens of ISPs providing simultaneous access to their customers. So effectively “law and order” must be effected by the ISP and policed by Openreach

Thanks, so on that basis about 72 Mb looks almost spot on the money for 95%, so it looks like TalkTalk probably cap at about or just below the Openreach rate?

And it looks similar on the download, 516 is just below the 95%, so again it looks like TalkTalk probably cap at about or just below the Openreach rate?

Openreach actually cap slightly above the upstream product rate.
With most providers you will see just over 75Mb/s throughput on the 550/75 package.

Talktalk seem to cap upstream throughput a few Mb/s below what it needs to be but it isn't the end of the world.

Interesting, thanks.

Do we know why TalkTalk cap it a bit lower?
