[John, is 45.127.0.0/16 one of the two blocks they keep, or is it
hijacked already? :) ]

The problem with that is indeed in that little part about "aren't using
them", if even only 50% is in use because one allocated it quite
sparsely you won't be able to quickly clean it up and return it.

For delaying the inevitable by what, a month!?

It is indeed really great that they took the effort to do so, but then
again, they where not always using this prefix, only during events, thus
it must have been quite empty. The fact that RIPE's RIS hasn't even seen
the prefix announced ever says enough about that part.

Doesn't mean it is not being used by other parties though:

45.127.0.0/16 	13767 	DBANK - DataBank Holdings, Ltd.	2009-04-10
15:43:59 UTC 	2010-10-20 14:11:43 UTC

One can of course wonder if they are supposed to use that or not.
The fact that they do not have reverse DNS delegation for it says quite
a bit already of course.

Maybe that is one of the two /16's that they are keeping to themselves,
seems to be used that way for over a year already. I assume L(3) did
proper checking.

Greets,
