If an Alertra station reports a failure, the next station will check it again in 30 seconds. After 3 consecutive failures from different stations, the site will be marked down by this highly reliable and efficient website monitoring alert service, and your contacts will be notified. The contacts you specify are notified again when the site comes back up online.
