Windows Azure CDN locations

I asked on the WebApps StackExchange forum a few months ago out of curiosity, if it is possible to know where a Content Delivery Network's servers are located?

The unanimous answer was that it is not possible to know unless the CDN vendor gives it out. Both the respondents to the question also mentioned that big CDNs don't reveal exact details.

I was therefore pleasantly surprised when I recently came across a Windows Azure Team blog post that lists all of Windows Azure CDN's (currently) 24 physical nodes.
