After a few network dropouts while playing Elite: Dangerous I was busy trying to find where the network failure was and decided I needed some help.  PingLog is a (very) simple tool that allows a network ping to a  specified host at the defined interval.  If it fails then it pings a secondary address.  The failure and subsequent pings are then logged.

I used this to determine that when I had issues to elite, local addresses where still reachable but the router was not – the problem is with intermittant interference on my HomePlug network.
