£864 per day or £315360.00 per year if the servers run at peak 24/365

Obviously this is a very rough estimate it is impossible to say how much power their systems will drain and I have no idea how much BT pay for their power but I assume it is a great deal less than my domestic rates; but it does provide a basic illustration. It would seem that power costs could be around the 1% mark when you take into account the £84M over 4 years.

That's assuming they still use the cookie option, without cookies Load Balancing could be a real problem.
The cookies were being used to prevent infinite loops 1% was the figure quoted I believe.

This was of course before this became Public knowledge, the first thing a User does is to try to block unwanted sites.

How can BT or Phorm detect & drop these loops in a hostile environment without cookies?

The Nebuad System may well have the same problem.

Sorry got the quote in the wrong position & my system always logs off the forum, so I couldn't edit it
