Operational means that all services work as expected.
We have divided disruptions to operational status into two main groups: spontaneous incidents and scheduled maintenance. Incidents are further divided into three categories corresponding to the extent of the problem:
1. spontaneously occurring incidents.
Degraded performance appears, for example, if our services have longer response times.
Partial outage appears for minor issues with accessibility to services.
Major outage appears for major issues with accessibility to services.
2. scheduled maintenance
Under maintenance is used for scheduled downtime or maintenance.
