There was some effort started at the last RIPE mtg to ensure that (at least for the European Exchanges) this data was collected and made available online. There are some issues with making such data available for US exchanges and I've not heard back about Asian ones yet.
I sometimes find it hard to comprehend the attitude of some suppliers. "Yes, we've got a service, that we might be able to sell to you, but we can't publicly tell you anything about it". If the supplier doesn't wish to make that information public themselves, then I don't see that there can be a problem with their customers publicly saying how much they're paying/where they're connected/etc, as long as their contract with said supplier doesn't contain an NDA covering such information.
I expect that at least for the Euro sites, we will have online in the very near future the types of data you are looking for.
That would be very useful, thanks! Simon -- Simon Lockhart | Tel: +44 (0)1737 839676 Internet Engineering Manager | Fax: +44 (0)1737 839516 BBC Internet Services | Email: Simon.Lockhart@bbc.co.uk Kingswood Warren,Tadworth,Surrey,UK | URL: http://support.bbc.co.uk/
