Re: FTTP Pings/Traceroute

I'm on 900/100 from Zen and . To BBC/Google I'm getting around 8 to 11 ms via WiFI 5 to 6 from wired and 5 from the router itself.

In reply to a post by UKFOB:
This was pretty much what i was thinking it should be given its full fibre and a new network. Shouldn't be any over subscription.

I'd be interested to see what any CF/Zen customers get in Leicester.

I did reboot the router recently for the IPV6 config to be added but still connected to the same first visable hop.

I doesn't necessarily follow that way. What is likely happening is the CityFibre connection is just getting you to the nearest point where it can hand over to Zen's own network, and from that point on it behaves like any Zen connection, i.e. you are bundled up with everyone else and treated exactly the same.

You may need to drop the PPP and reconnect several times to route hop, it can take several tries, although being FTTP no worry of DLM kicking in at least. You still end up seeing the same gateway(s), the route change happens at a lower level that isn't visible via traceroute except for seeing the change in latency to the gateway.

E300 / UKFOB

Depends on where his resilient node is and the routing to it., Your scenario only works where it is London / Manchester and you are south of Manchester by a significant distance. Because of Derby location it may route vis Manchester even if it is resilient on London. If they have a 3rd node ( Glasgow) it could be by there and even higher.. Direct routing to London from Derby won't be much shorter than going via Manchester due to transmission routes.

i thought they would of used AS8468 ex ENTANET network and not Vodafone's for CityFibre's network.

Few from Manchester that have IXManchester if any use to someone, Quite surprised BT dont have any public peering exchange points in IXManchester or any LINX Internet Exchange's only the one in London https://www.peeringdb.com/net/281

Cityfibre's residential FTTP network is wholesale layer 2, very similar to Openreach. All layer 3 (i.e. IP routing) is performed by the ISP.
