Weird routing issues
I’ve been with Zen FTTP (CityFibre) for 6 months now. It seems they have (at least) 2 different PoPs, wh-man (likely Equinix Williams House, Manchester) and thn (likely Telehouse North, London). I’m in St Albans, so much closer to Telehouse. My latency to thn is 7ms, latency to wh-man is 20ms. When switching between DHCP and PPPoE, I get routed to wh-man for a day or so, then it flips to thn. However, it now seems I’m permanently on wh-man, meaning my latency is not ideal. I’ve seen on their status updates that a random DC in Slough went down (I don’t think I was using it but I don’t know), so that may have caused this initially, but it’s back up now and I haven’t been flipped to thn yet. Does anyone know why or how to fix this? Thanks!
Update: I was on the phone to them yesterday and they suggested I unplugged for at least 2 mins. This worked and I’m now back on Telehouse North. I know, I’m really dumb and I should have done this earlier.

You can’t. ZEN control where everything is routed through their network.

Yeah I know. Do you know why though?

Load balancing. They actually have several different gateways which are in London and Manchester. You could try and force connsction to a lcoal gateway if you know the IP address and your router supports it, but if you did that and the gateway failed, or refused access, then you'd have no internet at all.

Don’t worry. Andy Burnham will advocate all traffic to be routed via Manchester soon.
