Yeah, I saw that a bit earlier and it did seem incredibly suspicious given the timing. Had I seen anything in the routing system itself forthat explicit /19 related to this I would mentioned it, but nothing there.
Amazingly, a query to the NOC at SES Newskies yielded a near- immediate response, which said they added it a few days back becausethey were updating some policies and noticed it existed in a prefix list for one of their upstreams, that it appeared to be legacy, and that they'd get
it removed. All the more reason RIR allocation authentication used to seed IRRinformation would be of value for routing policy specification, let alone
informational purposes. -danny
