my mrtg skillz are kind of lame, but this seems to show 2/3rds outage from
this monitoring point of view. It'd be nice if the aforementioned
'what/where/who' info was available for each monitoring point CYMRU
uses... So you could tell that from the SBC POV you were querying the XO
westcoast pod, from the APPS POV you saw the Verio CHI pod and from the
AT&T POV you saw the ATT local pod.

Anycast makes the pinpointing of problems a little challenging from the
external perspective it seems to me.
