Any IPs to ping

Hi,

I am looking forward to moving (back*) Zen with our migration/activation date confirmed for a few weeks time.

The sales guy I spoke to did say our exchange does have Zen LLU available, so hopefully it is over that mechanism.

Does Zen have a looking glass or can anyone suggest any IPs that I could ping from the remote services we use?

The spikes in latency we are currently experiencing with our current provider (basically Talk Talk Business) is terrible. This only started over the last 4-6 weeks, so coincides with the mass national Working From Home. Prior to that my current provider was great/fine.


[*Zen was our first broadband provider 20 years ago when 512kbps was the jump up from dial-up]

Not sure where it lives in there network but you can try "echo.zen.co.uk"

Perhaps?

https://dnschecker.org/dns/United-Kingdom/Zen-Internet

Or perhaps ping their speedtest page - http://speedtest.zen.co.uk

Thanks. Looks like that is one of their DNS servers.

Any idea on any of their DSL termination IPs? e.g. a gateway that my connection would see as its first hop. I assume if I could ping that, then that gives an idea of latency up to the final leg to me.

Nope.

Hi, my current gateway is 62.3.80.21 (losubs.subs.bng2.th-lon.zen.net.uk), my static IP is from the 217.155.0.0/16 allocation.

I'm on Zen's LLU network, my traceroute to google is

it was to google.co.uk

Thanks - I saw that
Wondering why it is ~12ms. I'm currently hitting that same IP around a third lower (TT Business/LLU).

I'm in cornwall will explain some of the ping time.

10ms on EE in the Midlands.

Brilliant - thanks. Those results are more like it. Good to see

I look forward to our migration over

Generally you'll get single digits on a good line nearer the south but you would move into double digits as you go further north. Its just inherent latency in the network with it all terminating in London.

Sheffield, although at my exchange Zen use Talk Talk Business backhaul.

Great - thanks

We are in London so am expecting it to be good then

Got connected.

With their router, getting a solid 6ms pings to 1.1.1.1
Solid 7ms with my own hardware combination.

And none of the silly random latency spikes that was happening with TTB (via Pulse8)

Really pleased.
Thanks all.
