That article was deeply mistaken.  50 was reasonable for older IOS with
bugs back in ... 2001-2003? I think.  under the auspices of apnic, gih 
has done serious study of network diameter [specifically in relation to
churn and background noise, but useful data here].  I'm a big fan of
belts and suspenders but would reccomend taking at least a coarse 
analysis of the path lengths seen in your neck of the woods from your
providers before setting a number.

Cheers,

Joe
