ASN's and Prefixes missing from IPv6 table

[Stephan Millet]

Firstly my apologies for the X posting.

We have noticed a sudden drop in the prefix size of the IPv6 RIB and the 
number of origin ASN's in the IPv6 network

Prefixes suddenly down from ~800+ to ~720
ASN's down from ~603 to 569

This activity has taken place in the last few weeks (see 
http://bgp.potaroo.net/v6/as6447/ 
http://bgp.potaroo.net/v6/as1221/
for a comparison)

Has anyone else noticed this ?
Has anyone noticed v6 reachability no longer working to some sites ?
Does anyone know if there has been a 'break' or 'restructure' or 'rehoming' 
activity take place recently ? (Was there a 'big' 6BONE turn off ?)

Any info would appreciated (on or off list)

Cheers
