have we figures about the frequency of changes in the root file?
The serial # changes twice a day. The contents hardly as far as I
can see.
Always wanted to check that, but since it is of interest on a
substantial duration never did.
It is very easy to check. Just pull over the zone file at a regulary
base and do a diff.
The only serious figure I have is that ICANN decided that three
months and half to update major ccTLD secondaries was OK (after
KPNQuest).
Document your figures.
Note that ns.eu.net was never dead, so I wonder what the relevance
is anyway.

PS. I wonder how soon someone will tell me I shouldn't be feeding ...
