All attemps to reach them are have failed.
Ticket open with MFN to request that maybe put a prefix-list on this customer..or maybe even max-prefixes..
Seems they're leaking their level3 transit routes to mfn:
eg: prefix: 64.12.0.0/16 (AOL) 6461 22534 3356 1668 8176 I
MFN in turn seems to be leaking it to all (or atleast most) peers.
Sigh.
