Yep we saw the same, every customer with old IOS had their sessions die
to us at the same time...   That always makes for an interesting time
when watching the NMS system...

We are seeing a much more sane path now:

agg2-sea-A>show ip bgp 94.125.216.0/21

Hi,

Yep, we see them too.  Nasty because there are lots of networks
flapping as the long as-paths are tickling old bug CSCdr54230, so even
networks not affected by the bug will be getting lots of extra updates.

Anyone with contacts at 47868 ?  Any upstreams onlist that want to bin
them ?
