Alerting across multiple sites with different business hours

Hi Mike, I had same issue and I signed up for Pagerduty (Free account) and connected LM with pagerduty account and created the escalation policies in the pagerduty to forward the alerts to different teams (in different timezones) and also configured a backup where in if no one is availble or acknowedging that alert in pagerduty app then route it to someone else.
