  1. Fantastic resources thank you, I found your site through Haroun’s great tweets. As a webmaster we need to be the first one to know about hosting downtime, so these tools are just great. I use pingdom and love it. I am eager to try a few of the others too.

  2. Very nice. I wrote a script in Google Docs to do the same thing and store the data in a spreadsheet. I won’t post the link here but if you Google “StalkMySite” it’s the first result. Check it out if you’re interested. :)

  3. A nice presented list, I must say! I would like to also personally recommend PushMon. It’s a free tool for monitoring applications, scripts and background jobs. All you have to do is call a URL. If PushMon did not receive the ping, it will notify you at once!

  4. If your an entrepreneur, designer, or have a small business and need to simply monitor a few sites with reliability and frequency, check out http://letsmonitor.com.

    Its simple and user focused, without filling you up with the same speech you see from every other enterprise monitoring service.

  5. Hi Sarah, please add http://www.uptimedoctor.com to the list.

    Most companies do not offer enterprise-grade (1-min interval) monitoring for free. For those who do, usually only 1 URL is allowed. Uptime Doctor is the only company that lets you monitor 5 URLs every minute, completely FREE. This is more than enough for small businesses, developers and bloggers.
