[Xymon] When Xymon is offline

We have a xymon server hosted on a local (dev office) server so that we can monitor our servers "from outside" - as customers would see things. Generally, it works great. However, the office connection, being a business class cable Internet, does experience some downtime, and when it comes back online, my phone is deluged with messages about the sky falling and all our services being down.

Is there a way for xymon to detect that it's off line and not send hundreds of alerts? Ideal would be to have 3 or more xymon server instances in a distributed wan cluster, and only generate alerts when a quorum of >50% has been achieved. Is this possible?

Thanks,

Ben
