Thats pretty awesome. Cute logo as well.

It would be great to add some more locations around the world.

If you add monitoring and alerts I would probably pay. Not that much as its already a corwded space, but I think a cheap alternative could get traction.

I wonder if its possible to have a business model of only charging when it alerts you to a site being down? E.g. we just alerted you to a site being down. Donate and we will do it again! Dont donate and I will delay my alerts by 1 hour next time!
