Has anyone experienced a problem where a monitor that is setup as a ping is disabled but an alert is still triggered? The monitor had been disabled for 30 minutes prior to the site the monitor was pinging went offline for maintenance but the alert still triggered.
How was the ping synthetic disabled? I have come across occasions where a user has disabled the synthetic from the monitor list. Although the UI indicated the synthetic was disabled, the synthetic was not - refreshing the screen showed the correct status.
This is possibly due to an Ajax request from the UI not completing, but the UI thinks it should change state.
