[re: francisuk25] [link to this post]

By looking at @Kenneth traceroute, i can see that this person is getting 5ms compared to what i get what was dated Nov 21 this year.
https://forums.thinkbroadband.com/fibre/4700159-fttp...

Im also Wired to the fritzbox, checked if interleaving was on but says Fast.

I cant see it been a router issue since the gateway at THN/Lon1 is about 7ms, so if i drop the PPPoE connection and get on thn/lon1, as you see can is ALOT lower compared to IXN/lon2

In reply to a post by pluralist:
Indeed, but it isn't the same router that has responded. Also tracing to cloudfare as opposed to thinkbroadband's Firebrick might not make a difference in theory, but theory and practice do not always agree. I'm sure you have been around long enough to have found that many times.

Afraid not. PPP can only terminate in one place at once. The hops responding are the devices terminating the PPP sessions so there's no IP routing in between customers and the kit responding.

Whether you're tracing to Cloudflare, TBB or New Zealand the first hop on Zen isn't affected.

In reply to a post by Ixel:
Interestingly this seems to happen if you enter www.bbc.co.uk instead of bbc.co.uk as the traceroute destination.

Tracing route to uk.www.bbc.co.uk.pri.bbc.co.uk [212.58.237.253]

It's because of the wacky CNAME resolution they use.

Probably they are using some geoIP-aware primary DNS server.
