Lowest Latency Openreach FTTP ISP?

What is the lowest latency openreach FTTP ISP?

Surely geographic location has a fair deal to do with it ?

I get 15ms to London from NW Ireland (Derry) - Always found BTs routing and latency great.

Sorry, I forgot to mention I live in London.

I mean if your london based most the ISP's should have data centres there, I believe Zen, BT do, can't speak for talktalk although i would imagine so.

Take a look at the latest ofcom report not much data but there is a bit, it gives a vague general trend even if it included various technologies although won't be bang on accurate it just helps you see which ISP's overall have lower latencies.

I live in the south west (not London) and always get exceptionally good latency given the fact my connection has to go all the way up to London and back. I can't imagine you'll have any issues with any ISP in London unless routing in their core network is somehow broken. Recently, I've seen a lot of latency and packet loss in BT's core network lately when running traceroutes/mtr to a VPS in London and putting my machine under a heavy load, there's none on my router which has an average of 0.1-0.2ms of latency but some on the next hop and this persists. I know they'll fix this, but just pointing it out.

How long ago did this start happening?

Within the past week and it only shows up under a high-load (just running a speedtest on speedtest.net or fast.com with mtr running in the background is enough to cause loss).

Some examples:

IPv4 mtr to my VPS whilst running a speedtest (no loss on the first hop this time, but I've seen that before).

Living in London your latency is likely to be 2-5 ms at max over any ISP to any London destination. To anywhere else depends on ISP interconnects and where you are testing too.

From London,once outside the UK sheer distance overcomes ISP differences within the UK.

Well I also live in London, and when I used my BT connection we got in the range of 2ms to 5ms (with the odd 1ms) to places in the UK, EU about 5 to 10ms (WoW EU Servers) I cannot test now due to I am now using a different provider.
