Yep, you're right. Looks like they might blackholing the /32 with a null
route on their network somewhere.
To mitigate the impact, I am sending 184.108.40.206/24 as a more specific
route through my other transit provider (15290) who does not transit with
1239. I am trying to limit the damage to just inside 1239 and those single
homed off 1239. I am sending 220.127.116.11/23 through Telus (852) who also
has transit with AS1239.
Someone else told me off list that Sprint usually blackholes with ACLs and
not NULL0 routing. So perhaps an IGP issue ? If so I would have thought
others would be seeing strange things as well.
