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.

All the best,

Pete

Alan,
Not sure what organisation you are from, but are you share details on that BT 
outage? 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.

Regards,
Neil.

The updates that we had regarding this was:

-The ducting has now been repaired
-The 800m of 160 is currently in the process of being pulled in.
-The new cable has now been pulled in and prep work has began.
-The ETR has now been revised to be between 01:00 - 02:00.

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!

just speculating wildly, was this a result of IPv6 deployment going wrong?
