IMHO it does not exist, if one looks at:
http://www.sixxs.net/tools/grh/lg/?find=2001::/21

I guess it just started to disappear from the routing tables.
The Green ASN's are providing GRH with routes, and both 6939 (HE.net)
nor 13944 are providing this route to GRH. Thus apparently they don't
have it. 3257 (Tiscali) does not have it either. 28747 (Realroot)
doesn't have it either, but 3344 (Kewlio), 16034 (KeConnect) and 16034
(NFSI) report they have it. 

Apparently it was first seen yesterday around 21:00
http://www.sixxs.net/tools/grh/lg/?when=selected&year=2005&month=04&day=11&hour=21&find=2001::/32

maybe it has since then been taken off the announcement list though.

According to RIS: http://www.ris.ripe.net/perl-risapp/risearch.html

it was first seen in LINX at RIS 
A 2001::/32 2005-04-11 18:58:05Z 2001:7f8:4::cb9:1

  2001:7f8:4::cb9:1 150 IGP

  3257 6175 6830 1299 3320 5609 6762 2914 2514

Withdrawals started at:

W 2001::/32 2005-04-11 19:05:35Z 2001:7f8:30:0:1:1:0:1853  0 IGP - - VIX

But some boxes apparently still have it and it is lingering as a ghost.

Nevertheless, AS2514 should never been able to announce that prefix in
the first place.

Greets,
 Jeroen
