According to
http://knowledgebase.demon.net/article/business-broadband-fair-usage-policy.htmlit seems that Demon are now FUPping their business users. The "Business Premium" package is still exempt though.
The FUP is of the go-slow penalty type as opposed to the surcharge type. So making it impossible to get any business done for the rest of the month, but at least the usage allowance is pretty generous at 100GB 8:00-23:00 and unlimited off-peak for BTW users and 200GB for LLU, so hopefully business users won't fall into the trap.
I'll be moving a couple more customers of mine away from Demon in the light of this, and Zen or AAISP will be the beneficiaries. I would expect that Demon are going to find that a fair few of their customers besides myself have already FUPped off before this point and jumped ship, since I get the feeling that Home users got pretty fed up when the first home FUP policies came in a few [?] years back.
As an example of the congestion inside their network for business users, I measured ~1Mb/s effective TCP inbound repeatedly in the afternoon using various of your favourite speed tester websites on a very short BTW IPStream Max Premium [Demon Business 8000] line syncing at >7000k) over several days. To my mind the position they now find themselves in simply shows the unsustainability of the way they have been running the show, promising a free-for-all in a world where a succession of bandwidth-guzzling developments for many have been seen and this now together combined with the beginnings of a slow growth in significantly faster new technology last-mile access pipes for at least some users.
Despite my perhaps harsh comments, I remain a Demon fan, in a sense. My attitude towards them is rather like the way I regarded Apple fifteen years ago, wanting them to do well again and turn things round, when it was evident that they had almost completely lost their way.
