In addition to John's excellent suggestions, I'd consider the possibility
that you're seeing configuration typos or transpositions.  For instance,
are you seeing a prefix being prematurely advertised by AS31000 which is
also being correctly advertised by AS13000?

Are these announcements, on average, shorter-lived than usual?

Do they advertise the same prefixes before and after the RIR has actually
allocated them?
