Reliable Alerts

All monitoring is performed in parallel from multiple test server network locations at every test interval. Only the failure of all simultaneous attempts on a particular test cycle are interpreted as a true failure of your target. Upon a failure, a retest is scheduled in the next minute. This system ensures highly reliable alerts that are resistant to false positives. Setting a suitable alerting delay can further suppress transients so that alerts are only sent when you must take action.
