An automated alert sent to an on-call engineer requiring immediate attention.
Detailed Explanation
Historically derived from physical pagers, a 'page' is now an inescapable app notification, SMS, or phone call designed to wake an engineer at 3 AM. A valid page indicates a critical, user-facing outage that cannot wait until morning.
If a page is actionable, it is an incident. If it is unactionable, it is just harassment.
