It does not work well at all when using a busy Internet connection. It constantly tells me that my servers are down although I am SSH'ed into one and I am happily editing a PHP File, pinging it from the same phone yields success, too. I tried this on a coffee shop's WIFI and my current synchronous 30/5 when the network is busy you get constant alarms.
Pretty good server alarm monitoring tool. And its free and actually works and no false positives
# 1.0.4 Release
