Detecting partial outages

Is there any way to configure Nagios to detect and ignore partial outages?

Specifically, I have multiple datacenters for my production service, and
then two separate locations from which I do monitoring.  It's very rare that
any of the production datacenters goes down, but it does happen on occasion
where one of the datacenters becomes inaccessible from only *one* of the
monitoring stations.

(In other words, the datacenter is up and running fine, and appears
accessible by real users, but looks down to one of my monitoring stations.)

Is there any way to configure Nagios to detect this sort of "partial outage"
condition and ignore it?  I only want to be notified if it's reported down
by *both* monitoring stations.

Thanks!
