To make it easier to understand the severity of an incident, we have created a severity scale.

Severity scale

CriticalThe service is unreachable or unusable. For example, two consecutive heartbeats of an HTTPS monitor failed.
HighImpact on the service related to the incident is noticeable and requires action.
MediumThis severity is important, but does not immediately impact service availability. It is assigned to incidents such as a certificate expiring in 14 days.
LowEvents that happened, but do not impact service availability directly. For example when a certificate change was detected.
NonePurely informational, not in use at the moment.
