I am not sure if my note is strictly to the subject.

The Men and Mice
 http://www.menandmice.com/dnsplace/healthsurvey.html?DHS1100
indicates enourmous percentage of misconfigurations, see quotation.

I do not know how many of them are related to the case quoted above,
or, more complicated, to the name servers accross TLDs.

International Comparisons of "Domain Health" 

Highlights

In March 2000, Men & Mice conducted a comparative Domain Health 
Survey for 8 selected countries. Random samples of 2000 zones 
were tested for United Kingdom (.uk), France (.fr), Canada (.ca), 
Australia (.au), Spain (.es) and Norway (.no). A random sample 
of 1000 zones was taken for Ireland (.ie) and 500 zones for 
Iceland (.is). It appears that Canada and United Kingdom have 
the largest number of incorrect zones (read about critera for 
errors in Methodology) or 70.30% and 70.05% respectively. 
A Domain Health Survey for .COM in February '00 shows incorrect 
zones as high as 72.5% (see figure below and further information here). 
The best condition was in France with 29.35% of incorrect zones. 
Close to France was Iceland with 32% incorrect zones, and 
ranking number three was Norway with 36.10% of incorrect zones.
