Yes it does seem that they were in preparation for the trials. But the webwise faqs, contact form etc are bog standard customer service stuff. You will probably find the same contact form embedded in loads of BT pages. the form is just a portal into the CS system which will probably verify that the customer details are known and then attempt to make an intelligent guess about where to send the query. It's very unlikely that anyone is going to tell you anything specific about their configuration in response to a CS query. Much more likely to get a standard 'very sorry should be better soon' or 'don't worry your pretty little head about it'. For UK Government sites this (the network topology) would be restricted information in any case, many big companies take the same approach.
There you go - they are a Siebel user
