Absolutely true, let me take Swedens level-1 DSAs as an example :

6 DSAs with a reachability of < 10 % ( in fact it was 0% for all of them )
and
4 DSAs with a reachability of 100 % .

Now, who are managing the 6 non-reachable DSAs ? 

Well, an investigations shows that two of them are experimental DSAs, put
up for training of DSA managers and for trying out new things, not surprising
that they might be unavailable for a week.

The other four are managed by four commercial companies, that participated
in a X.500 pilot excercis sponsored by the government 3 years ago.
A valid assumption would then be that all of them left the arena when
the funding ended and they did not see any shortterm gain from keeping
their part of the pilot up and running.

So, Swedens figures might look bad at first but when you start to investigate
further you find that they are almost as good as could be expected.
