Windows – Simple internet connection uptime monitor

I need to just monitor how often an internet connection goes down – and for how long.
I was going to just write a bit of python that pinged 8.8.8.8 every minute but I thought there must be a util that does this – and produces a nice report

But this is a branch office with a simple SOHO type connection, no SNMP router, Windows only, must run on a desktop machine that isn't dedicated to the task.

Don't need to know capacity, ping latency or anything – just a report of how many times it was down for more than a few seconds to wave at the cable company.
