Performance monitoring

[Mehmet Akcin <mehmet () akcin net>]

hi there,

I am trying to find out what everyone is using nowadays for
performance monitoring.

Thousandeyes, Perfops, Ripe Atlas, Cedexis are some common stuff I
have used in the recent past to see DNS/CDN performance , anything new
out there that is worth giving it a try specifically focusing on
distributed DNS performance?
