You, and I, are in the wrong part of the country to get 10ms to London where most of the servers live sadly.

Obviously you can pursue it however from Openreach's point of view this isn't a problem, and just wanted to make you aware you would potentially be charged.

You may find this gets sorted when G.inp is enabled on all the ECI kit.

No, not quiet true, I live far North about 350-400km from London and this is what I am getting right now. I used to get about 11-12ms before and it stayed that way very long time.

Interesting. You appear to have the lowest latency VDSL I have ever seen.

Everyone else takes 4-5ms to get to the exchange due to the delay to modulate and demodulate, and the 400km round trip to London even if it were straight line with no routers in between would be another couple.

My own latency to an exchange 10km by fibre route away via an HG612 and Huawei DSLAM, line with G.inp only, is higher than yours apparently is through the BT network and 400km.

I have seen FTTP with your numbers but not VDSL. My own BT connection, no G.inp, managed 10-12ms or so to London despite my connecting to an MSE then a 21CN metro node a few km away.

That I can just about believe. Very good connection. As good as FTTC gets.

BT?

My BT Retail line when I had one came close to that latency. Plusnet not so much! My TTB line now is a little higher but am very interested in how someone on VDSL in Liverpool is managing 4ms to London.

Plusnet.
My BT line is currently at 20ms due to interleaving on the upstream but it did do 9ms before.

Im a new Plusnet customer so my lower ping may be due to their new network setup.

Excuse me. Did you mention me or? I am from Liverpool and I manage to get 5ms to London right now. Used to be 11-12ms normally on fast-path, no idea what happened but after that resync its 5ms. When I used to monitor my stats with HG612, only things that I remember were Interleaving of 1 1 and delay of 0. I also used to have different DNS on 2nd and 3rd hops like 217.xx...

Anyway, I suspect a massive amount of ES without G.INP so this may eventually come back to 12ms.. And internet feels really sluggish especially at evenings when SNRm dropped to 4.6dB...

Oh, and by the way my mate gets about 7-8ms to London with Sky 80/20. Nothing special with it imo. 12ms is still a bit high latency to a servers in the same country imo. We are not on dial-ups...

A broadband quality monitor would be interesting for sure.

its around 15ms over bt wholesale.

Oh I know the network you are using there reasonably well. I helped build it

[N0STIE]

Can't use broadband quality monitor with dynamic IP. It gives me an error and 100% packet loss

I only could do speed test on that website.

[niemand]

No worries.

Thanks for confirmation there's something weird going on nonetheless. The TBB latency measure showing 1ms is odd.

His copper line must actually be a line spun of gold directly to TBBs tester.

Ive split this topic off so as not to distract from JoshSheps thread here.
More so, because I too find this puzzling, and Ive also never seen such low latency outside of London on 21CN.

I was beginning to wonder if BTw had installed a brand new core node at Liverpool, but a lookup on the IP address at the 4th hop (31.55.185.196) resolves to BT-21CN-TMAN-V2, so it still appears to be entering the Core at Manchester.   

It takes me 4/5ms to get to my head-end exchange where there is an MSE bRAS.  4-5ms is the least Ive ever seen anywhere to get to the MSE bRAS  (Its usually about 6-7ms on the old RAS). 

I join the core at Preston, so perhaps add on an extra 1ms more than Manchester.
But it still takes me 6/7ms to get from Preston to Colindale over the core.

I'm at a loss how to explain whats going on here, and wonder what BT are doing now.

[William Grimsley]

What I can't understand is I've got a fastpath line and my pings are between 20 - 25 ms!
