some time ago i sent an email to the list telling that we have a very
congested 12 Mbits link to the US, it still are, and will be until the
OC3 get up and running. To all the ASs that peer directly with us here
in Brazil, our server is the best one and appears to solve the problem
very well to regions of the net not so well connected to the core like
ours.

This is our verification of one of the auth servers for COM.BR located
outsided of Brazil, just for time comparing.
