When I force a traceroute to originate from our MICE-facing connection, the first hop is 206.108.255.50 (AS32609 aka CNS). Any reason why?
To making things more interesting, Incapsula-destined traffic goes via Paul Bunyan. Here's just one example:
traceroute to www.yamaha-dealers.com (45.60.73.16), 30 hops max, 60 byte packets

The reason I stumbled across this is because we've had more than a dozen customers over the last month complain about access to Incapsula-protected sites. Packet captures show TCP RSTs coming from the far side.
