Just off the top of my head -- You could have each monitoring station
report its status for each datacenter to each other and use
"check_cluster" to set thresholds on the monitoring stations stating
that both services have to be down in order to cause an alarm.

Of course, I'm sure someone will swoop down from above with a better
answer.
