I stand by my assertion that most people do not run 
traceroutes all day and watch for it to change.

That some people are diligent does not change the fact the 
overwhelming majority of people are not.

Or the fact that with the right placement of equipment (read 
"luck") and cooperation of networks involved (read 
"laziness"), even a traceroute won't show any change besides 
additional latency.

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.
