Need Software to Monitor Internet Uptime

Net Uptime Monitor is a really simple Windows program that continuously tests your internet connection and writes a plain text log of every failure - when it starts and how long it lasts. No complicated setup - just install and run. http://www.netuptimemonitor.com

MRTG is an excellent program that does this. It is free and it has the ability to monitor a great many things.
