Abovenet receives /16's from a customer, who is the upstream of Manawatu.
Abovenet duly advertises these /16's to its other customers, and its peers.
Abovenet also blocks all traffic to/from ORBS, due to AUP violations.
Manawatu is ORBS's provider. Abovenet has done nothing to interfere with
the /24 cutouts Alan is describing below.
