Pager-Not-On-Phone Incidents

Paged but didn't get the page. The failure modes and the safeguards.

Failure modes

Phone DND. Phone dead. Phone in another room. App not running.

All real; all happen.

Multiple notification channels: phone, app, SMS.

Acknowledgement timeout escalates to backup.

Quarterly: page yourself. Verify everything works.

Most pager tools support test-page.
