If you hit https://web.mail.demon.net say 3 times chances are at least 2 of the connections you'll get a front end server that has webmail certificates to expire. I've given demon 2 days to fix this now but as an ISP and internet copmany to allow the SSL certificates to expire on the majority if not all (yesterday some of the front and boxes - a minority appeared to still have valid certificates) to expire is just shocking.
I'm surprised there hasn't been a little more of a story on say theregister.co.uk about this.
