Rightly or wongly, I've come to the conclusion that using the service username bypasses 21CN.

Doing this drastically improves my latency (30~ > 11~) and removes 3 hops from trace route.
Still using powerline adapters so deduct 2-3ms from everything.

Code: [Select]
Tracing route to bbc.co.uk [212.58.246.103]
over a maximum of 30 hops:

  1     3 ms     2 ms     2 ms  BH5A_Bridged [192.168.1.254]
  2     *        *        *     Request timed out.
  3     *        *       12 ms  31.55.187.197
  4    13 ms    13 ms    14 ms  31.55.187.216
  5    13 ms    12 ms    13 ms  195.99.127.172
  6    13 ms    13 ms    13 ms  195.99.127.52
  7    13 ms    13 ms    12 ms  peer2-xe8-1-1.telehouse.ukcore.bt.net [109.159.2
55.103]
  8    13 ms    13 ms    13 ms  194.74.65.42
  9     *        *        *     Request timed out.
 10    14 ms    14 ms    14 ms  ae0.er01.cwwtf.bbc.co.uk [132.185.254.93]
 11    16 ms    15 ms    15 ms  132.185.255.165
 12    14 ms    14 ms    14 ms  fmt-vip132.cwwtf.bbc.co.uk [212.58.246.103]

Trace complete.

We have at least two users, on BT Internetz, showing identical behaviour. At least a 10ms increase upon entry to the host labelled '21CN'. For me, this was a tripling of latency. 11ms became 30ms to bbc.co.uk.

Newt, your 21CN node has 'mr' (Manchester?) and mine showed 'bm' (Birmingham?!) despite being spitting distance from Cardiff / Bristol.

I guess none of this matters if BT Retail have bought all their transit at two nodes at the other end of the country and have the ability to tunnel traffic through devices that have probably been in service since the dinosaurs roamed the earth?

Do we have any other BT users on 'ere? Care to share trace routes? :)

Brilliant, thanks :)

You're going via 'bm' too it seems.

Where are you based, John?

Hi boost

Leeds West Yorkshire (remember reading the posts about us in Yorkshire ! :) )

It's a hub3 running firmware from 2012.

The only issue I'm thinking about is connected with our static ip (5 ip) and if they will still work. I guess so, as routing still shows them.

Many thanks

John

Hi

I can confirm that my 5 ip no longer work external and I have reverted back to HG login.

I can also confirm that our latency was half of the HG login, as detailed in Sam knows pic. Sorry, will post pic if needed, I'm not allowed too due to restriction on mobile, but Sam knows app shows latency at 10ms where before it was at 20ms.

Lastly, our gaming experience improved whilst using green-light username - or so it appeared to, but I think that's because I'm not a good at games.

Many thanks

John

I tried the green login, still hit 21CN (note, trace is over wifi not ethernet)

I'm guessing that only works for BT Business? Perhaps there's a similar trick for home users...
