Monitor ISP Connection Uptime

[Collider]

Looking for a free windows based software to monitor ISP uptime. Pretty simple just log times when things go down and for how long, any additional features would be icing on the cake but appreciated.

In my own searching I came across Net Uptime Monitor but its not free:

Any free options out there?
