Re: Horsefeathers -- was it a DDOS or a failed upgrade?
Same here. which is normally an indecation that the local control node can't talk to the ISP auth systems.
Normally it's ESR(number).sheffield returning IPs instead of BT broadband's systems.
I used to get it with demon as well, when sheffield lost contact with demon/anchorage house, and again, I'd get a PPP login with a 172.16 address.
Had 5 clients down and 2 not down but slow. Which looks again like a reauth happened on the 5, and nothing was reponding, hence they went down.
