The point where someone who isn't you is both hijacking your ASN *and*
someone else's prefix? Have you confirmed that the hijack actually
came from UDel, that the AS path matches one that's legitimate for
UDel? The guy hijacking your route doesn't have to list just one AS as
the origin; he can' list an entire chain.
