Customers of UK ISPs such as Sky Broadband and TalkTalk are this morning being affected by a loss of broadband and phone services across several exchanges in East Scotland, with some pointing the finger of blame at a damaged core network cable from Virgin Media.

My neighbours Sky FTTC is down.
My BT FTTC is fine.
ESDAL exchange (ES part = East Scotland)

Didn't they have an MSO a couple of years ago in Eastern Scotland? iirc the problem is they use a core ring topology and only 4 of their supernodes has much redundancy - even that is parallel rather than meshed. Pretty much everything above Edinburgh PoP (and Glasgow on the west) basically just the one route. :/

Where is 'East Scotland' ? there is a lot of eastern coastline. Could be next to Berwick, could be Shetland.

The ES exchanges cover quite a large area, but are predominantly East central Scotland. Edinburgh, Midlothian, East Lothian, Fife and Dundee all have exchanges starting ES.
I've no idea how widespread the outage in question is.

Most LLU exchanges outside of major cities are daisy chains of a bunch of them connecting via the final exchange in the chain to a POP.
No resiliency at all. Loss of one link means everything between the break and the end of the chain, from the POP, goes down.
This is an economy required to sell cheap LLU broadband.
