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
Paths: (1 available, best #1, table Default-IP-Routing-Table)
 Not advertised to any peer
 11537 25973 40430
   198.108.93.41 from 198.108.63.41 (198.108.63.41)
     Origin IGP, metric 905, localpref 110, valid, internal, best

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?)
