Just to add to this. The wider issue we all experienced is looking to be peering / bgp as the problem (As we suspected)
https://www.ispreview.co.uk/index.php/2020/04/intermittent-internet-connectivity-woes-strike-virgin-media-uk.html "Data provided to us by ThousandEyes has helped to track and trace the outage, or at least most of the related disruption, back to Liberty Global’s related UPC Broadband network (AS6830). You can see this a bit better with the visualisation below." (Have a look at the article) "The AS6830 network operates a lot of key peering arrangements with Content Delivery Networks (CDN), as well as other major UK and international networks (e.g. Akamai, Level 3, Telia, Cogent and about a thousand more like them). The visualisation shows that connectivity was disrupted to a number of those significant destinations. We now have a better understanding of where the issue occurred and why there were so many outages, although I’ll reserve writing about the detail of this until I can get some concrete confirmation on the problem itself." Anyone got any further information? Kindest Regards, Matthew Mercer ________________________________ From: uknof <[email protected]> on behalf of Neil J.

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.
