i read the mixp website really carefully;  it doesn’t have any such 
claim.  in fact the list of peering participants lists many more 
networks than these.

why would you assume this?

not all networks might agree :-)

there are definitely *not* 30 ASNs in operation in mauritius.  you’re 
probably counting all afrinic’s ASNs - including the ones they use for 
anycast, that are not, ttbomk, even used in mauritius.  and networks 
that were made allocations but don’t use them.
