Paul - I'm still eagerly waiting your reply to Patrick's questions.

Here at least we finally have something to read other than relying on  
blind faith, but
the author is so convinced DNS based GSLB doesn't work[1] (and gives  
good examples
of why it doesn't).  However, these are all pretty much theoretical  
examples, and there's
no explanation of why DNS based CDNs do in fact work so well in  
practice[2].



[1] FSVO "doesn't work" that is...
[2] I was going to say "appear to work so well", but that's unfair  
use of sarcasm - I know just how well at least one CDN works :)
