It's an old "ping script" that I've had kicking around for years.

It simply checks a couple of different locations every 10 minutes and 
if it fails trys again in 2/4/6 minutes.

Data analysis is actually limited to a humungous log file, grep and 
tail, which gets triggered if it fails.

It's one of those -- ok, this is good enough -- type tools.
