Sky bought the network to get the 400 000 subscribers and migrated everyone to their network, closing the O2 setup. I left, moving to TalkTalk, a network which gives out a different ipv4 address every time it retrains, two or three times a day at present, using their proprietary dynamic line management unchanged.

What other information could I collect if I find that PPPoE isn’t coming up reliably?
re: HEnet tunnels not coming up. There’s an easier way to reconnect the tunnel by going to a HTTPS link. It’s described in the IPv6 Tunnel page on the wiki: http://www.bufferbloat.net/projects/cerowrt/wiki/IPv6_Tunnel (Check out step 3, manually re-establishing the tunnel)
