Alan. While it isn’t technically confirmed of course, it appears very evident that your service is only resilient as far as fibre in ground and local pinch points are concerned.
If VM have taken a BT EAD back to their PoP, or even a BT exchange based VM “rack”, the issue here is your account manager or VM technical architect who hasn’t considered PoP site resilience, not Openreach. I can name half a dozen “pinch points” in this area where the trunk Openreach and VM ducts run the same side of an A road for example and three VM PoP sites, including the regional head end that have nasty points of none resilience. Or on the flip side, that a.n.other brand of Ethernet tail provider uses VM for some areas of national backhaul for example, in the same fashion that another recognisable Ethernet tail provider uses SSE. Ultimately the only person who can be fully calculated in the risks and costs associated with a twin provider would be yourself, to go and ask if carrier X is utilising VM backhaul, or whether VM have taken your EAD cct to the same single ended PoP site as your VM NE service.

There should not be a situation where we lose FTTC/G.FAST/ADSL all at the same time from a single fibre break. If that happened something else went wrong and I’d want to take a look at it.

I'm assuming that this was 800m of a 160 core fibre. It is a little worrying how susceptible Telford is to this, and how poorly connected things are around here on both BT and Virgin sides. So in the last 3 weeks, we've had an extended outage on all FTTC / ADSL / G.Fast based broadband service due to a single fibre break on the BT(O) side; and now a single fibre break has taken out all VM services into the same area. You would have thought that the infrastructure would have been in place to be more resilient than that! Alan On Wed, 29 Apr 2020 at 11:16, Neil J.
