I use Pingdom, but wish they could monitor more frequently for exactly the reasons you mention. In theory my site can be unavailable for several seconds each minute, without showing downtime in the stats. I signed up for your service, but looks like it is invite only right now?

I think most peoples invites have been approved at the moment.

We have a big release scheduled for Feb. Some cool new features like custom useragent strings and PagerDuty integration are going to be pushed out. We're excited :)
