A couple of years ago I discovered that I was paying Demon well over the odds for my broadband domestic tariff - which I had had since 2003 at £24.99 a month. Unfortunately they would not move me to one of their cheaper domestic tariffs - as they were no longer signing new customers for those.
So I ended up with a Demon business "lite" tariff. A lot cheaper than I was paying previously - with the welcome bonus of a guaranteed UK help desk.
Would have preferred a dynamic IPv4 address - but their business tariffs are always fixed ones. With no need for incoming connections - it would have been nice to have a bit more protection against a DOS aimed at my Demon sub-domain.
