While I understand that in the face of IPv4 exhaustion long quarantine
periods are probably no longer a good idea, I think 6 weeks is
shockingly short.  I also think to blanket apply the quarantine is
a little short sighted, there are cases that need a longer cooling
off period, and this may be one of them.

I think the RIPE membership, and indeed the policy making bodies
of all RIR's should look at their re-allocation policies with this
case in mind and see if a corner case like this doesn't present a
surprising result.

Correct me if I am wrong, but with RIPE's pool nearing exhaustion (in as
little as 3 weeks, depending upon who you ask and how you count) isn't this
sort of a moot point?  I suppose this block could have been moved to the
back of the list instead of randomly re-allocated, but would a few more
weeks really have helped?


Perhaps it should not have been re-allocated at all, rather than cause
the unsuspecting allocatee trouble they would not have seen from
clean(er) space.
