Sever Uptime Monitoring Tool

[Possibility]

Hey everyone,

I've been having some problems with the amount of uptime on my server, however everytime I mail my host and tell them that I couldn't access my server for X amount of time today they say that it must have just been on my end. However, I do not believe this, as all other websites work on my end except for any hosted on their server (including their own). So I have been looking for a free uptime monitoring tool how I can have some real proof. Does anyone have any suggestions? Preferably it would be one that ran through a website instead of downloading an application, but either way, as long as it is free.

Thanks!
