Pulseee uses a distributed monitoring system to negate false-positives and provide a layer for multi checks.
All primary checks are made from the main engines in Australia East. However, once a downtime is detected, secondary requests to verify this downtime is sent from remote nodes that are located in different regions primarily Australia Southeast.
If the monitoring works well for you, there is no need to take any actions. But, if you get any false/positives, there is a strong chance that the IPs used are blocked by your hosting provider.
Please make sure that you whitelist these IPs so that any requests that Pulseee send are not blocked.
