My hosting company have had some stability issues lately, so eirikso.com and all my other sites have been down a couple of times.
To get an exact idea of how big the problem is I started checking out a couple of services that can monitor your web site and alert you by mail if it is down.
I found several solutions. Here are the two that I am currently testing:
Montastic. Completely free. Lets you add up to 100 web sites to monitor. You get an email if one of them goes down. You can also subscribe to an RSS feed with status information.
SiteUptime. Free for keeping an eye on one site every 30 minutes. Gives you an email if it is down. Stores some data and details so you can keep an eye on the total uptime. Commercial version available with more functions.
Do you have any other suggestions? I have a couple of servers running 24/7 at home as well. Is there a simple application that I can install on my computer that will check on a web site at regular intervals?
