Reading this thread with interest and got me wondering.

Had an active FTTP connection over Openreach Fibre to Zen since 13 Jan 2018 (previously their LLU ADSL since March 2014), portal gives a plexus migration date of 18/1/208

Had a GEA migration in April 2021

Up until last week I would see the gateway reported as either -vt1.cor1.th-lon.ptn.zen.net.uk or vt1.cor2.th-lon.ptn.zen.net.uk

On checking the router logs (fritzbox 7530) on Wednesday I noticed there'd been a ppp drop about 4 in the morning (I'm aware of the router setting that allows you to specify a ppp session reset and mine is set to between 8-9) and the gateway was now showing as lo0-0.bng5.thn-lon.zen.net.uk
This has changed a couple of times when the router has reset ppp but it’s always one of the ones denoted as bng
I assumed the cor1-vt1 was Huawei kit since I’d seen it for a number of years since I was moved onto Plexus but after reading the comments here I’m now not so sure, I wondered if it was a movement onto Cisco or Juniper hardware as a result of the Government directive that Huawei kit has to be removed from networks by 2027.

Anyone know what I was connected to previously?

Just asking purely out of interest (I’m aware thn-lon indicates it’s in the Telehouse North DC in London)
Thanks

I'm in TW2 and connected to vt1.cor1.lond1.ptn.zen.net.uk.

My Zen supplied Fritz!Box 3490 reports the gateway as being 51.148.72.21 and that's the reverse DNS for vt1.cor1...

Unfortunately I'm currently experiencing 5% packet loss to 8.8.8.8 and nearer 10% to 1.1.1.1 and by BQM is a world of red! Plus, my tested have all be over wired Ethernet, no Wi-Fi.

I've sent Zen support an email this evening.

Hi

Unplug the router from power for two minutes to allow the session to drop.

Plug back in and wait 5 minutes or so, fixed issues on a number of ISPs by doing just that and Zen's own support message suggests restarting the router.

It could be a gateway issue but it could just be a session issue.

Thanks. Could well have been a session issue.

I pulled the VDSL cable from the master socket, gave it 5 mins and then reinserted it.

Now a 100 ping test has zero packet loss.

Strange.

Glad it got you back up and running
