We are checking Amazon S3 where we store some images, and occasionally the connection fails. We have found that it is usually a temporary problem and service is back almost instantly.

Unfortunately by then Simon has fired off our script and sent us an SMS.

So is there a way to tell Simon to ignore the first failure and check again a 2nd time maybe a few seconds later alerting us only if it fails twice in a row?

or any other suggestions to combat these 'sort of' false alarms?
