37Signals benchmarks uptime vs five leading webapps

So, like any stats, take them with a bit of salt.

You can configure it to send POST data and expect a particular response, but there's no way of telling (other than "yep, that's what we're doing") whether someone's uptime stats are based on that sort of check.

We recently started a web monitoring company (in beta) http://www.verelo.com to tackle situations just like this. Pingdom monitors every 60 seconds, its just not enough if you want to make claims like "we were only down for 6 minutes". If you want to make claims at a single digit minute level you need to check more regularly, and your checks need to be robust. We offer monitors that check as regularly as every 5 seconds.

We're going to monitor those same 6 sites for the next 30 days using our service at Verelo and provide comparative results when the next 37signals blog post comes out.

Y'all can see how there's been an increasing of 37Signals posts lately.

I signed up to check if they really do. What pingdom does upon sign-up with your email id they send a password via email.

I have a high opinion of pingdom & I was expecting them to enforce change of password during first login, but that did not happen!

  I didn’t think it was a very long article? Your first comment 
  missed the first paragraph and your second comment missed the 
  second paragraph. There’s only two more paragraphs to go, so 
  please take a swing at them :)

Well as usual I feel like the guy who rants all over the place, hehe.
