Does anyone have any recommendations on public services that will monitor and show uptime on a server? (besides netcraft)

I'm looking for something I can use to monitor uptime or downtime on some of my servers to I have some 3rd party stats to display to customers wanting to verify past status before they sign up for hosting.

How about Alertra?

Here are a few companies. Some of them are free.

alertra.com
host-tracker.com
easymonitor.com
internetseer.com
servermojo.com
siteuptime.com

Great guys, thanks for the suggestions. I had a couple of those I found through google, but there's a few I didn't see. I'd like to get a diverse sampling from different places. That'll help a lot.

If anyone know of others, please continue to post. I want to get a look at as many as I can.

siteuptime.com is good for being free.

Siteuptime.com does seem like a good one, considering its free and all.

Does anyone here use any of the other ones?

Free is not always good. I tried them out and made payment to monitoring every 2 minutes and got lousy results.

oh really? I'm about to try the servermojo one, its free and i'm cheap

They each look like they have some pros and cons. But I've got some links I can show potential customers now to help build a bit of confidence.

Thanks for the recomendations guys. Much appreciated.

glad we could help you

ServerMojo has been good to me - caught a http downtime, and then noticed when it was back up 15 minutes later, so they don't just do a ping every hour like some other free alert sites.

If they could tart up their site a little, and give a link to your site to show customers, and also show the response time.. it'd be brilliant and I'd use it for everthing!

i just game across another free one (really good)

Hperspin.com is fairly cheap and very reliable.
