Yes, but I see that Randy has switched over to 3130 <poisoned AS> 3130, 
which should at least keep a few alarms going off since Randy's AS is 
the so called origin AS (as if people don't do aggregates or truncate AS 
Paths (actually, there are some sections of BGP4, which probably don't 
get used as often as others would like)).

I'm now extremely curious if alarms were just going off since the 
right-most AS was the trigger, or if they go off just for the AS showing 
up in some unfamiliar path.
