Free website monitoring services: montastic.com, mon.itor.us, internetvista.com
There are several online services that warn you when your website is down or too slow. Here are three free services I tried (”free as in “freemium“). Feel free to add your findings or experiences…
Mon.itor.us

- mon.itor.us has a bafflingly beautiful self-updating dashboard with response time graphs and reports…
- notification via (one or more) e-mail addresses and rss
- they also have web and desktop dashboard widgets, and offer visitor tracking (you need to embed a snippet of javascript code) as an extra
- build your dashboard by adding your collection of modules - in the same ajaxy way as a lot of personal startpages (Netvibes, Google/ig…) do nowadays. Have a look at the demo
- the paying version of mon.itor.us is at monitis.com
Montastic.com

- Montastic really is as easy as you see in the screenshot… you add websites … sites are checked every 10 (!) minutes, you get an email when they’re down
- widgets for desktop notifications here as well
- on the other hand: the information provided is really basic: nothing more than “Website status: unreachable“. Slow page loads (+ a few seconds) trigger a notification - so I get a lot of notifications due to the often slow database connections at Dreamhost …
- ironically, Montastic.com was down itself at the time I wanted to take screenshots last weekend :-) - but that was the first time as far as I know!
- Montastic is completely free - there’s no upgrade plan. It’s built by a bunch of enthousiasts
Internetvista.com
- Internetvista has been around for some time and is the oldest of the 3 services
- the free version is limited to website monitoring with email notification
- main advantage: check for a specific phrase in (the first 4 kb of) your output. This makes sure you get notified when your website performance is ok - but the pages produce nothing but error messages instead of the expected content.

Thanks for the roundup pascal. I already knew montastic, but after reading this article i’m going to give Mon.itor.us a chance

At the moment, we’re already a bit sceptical about the Dreamhost uptime. Now we can see if it’s worth the trouble to move all our real estate to a more reliable service.
Thanks for this lineup!

As far as I have experience with it (mainly http://slforum.be) Dreamhost’s main problem is that databases are on a different machine… db connections are _really_ slow. (Pre)caching could help (if it makes sense for your particular app).

Another quite new (and might I add funny in a way) one is http://monitwitter.com/. I think you can guess how it works by looking at the name ;)

Quite happy with http://host-tracker.com/ myself.
Every minute checks possible and a nice uptime button if you feel like it.
