This is interesting. According to the router proxy, NLR sees the route as:
1103 20965 11537 10578 14325 14348

That's SURFnet - GEANT - Internet2 - NoX - OSHEAN - URI

I don't think that SURFnet should be sending that prefix to NLR at all; 
probably an error at that BGP connection. I'm copying the NLR NOC on this 
note so that they can have a look at it. . .
