GSLB.me sends realtime alerts in case your targets become unavailable, or available again after an outage. Whenever critical infrastructure components fail and recover, administrators are provided with notice of important events.
Alerts can be delivered via one or more methods simultaneously, to make sure that full feedback is provided from GSLB.me back to your monitoring infrastructure / Network Operations Center.
