Bingo!
Latency is the magic word and that *IS* measured by a lot
more people than do traceroutes. Unless the attackers are
lucky enough or smart enough to do their dirty work from
a server that is reasonably closely colocated to the router
that they exploit, you *WILL* see latency changes. 

It would be wise to change the process for investigating
latency increases to include examining routers for this
BGP rerouting exploit.
