Thanks for bringing this to our attention. We verified that this was indeed "borrowed" space and dropped it from the customer's prefix-list.

Cheers,

really? I see it traceroute to mzima/colo-jax.. and routeviews shows
origin AS40430:

show ip bgp 68.234.16.1
BGP routing table entry for 68.234.16.0/20

note mzima has some whacky routing loop going on there as well for
some of the  /20... (agreed that there are no ARIN records/whois for
this block, perhaps it got reclaimed?)
