15. > Incident Priority
Lightower uses three priority/severity levels for service issues:
Priority 3
A Priority 3 incident is a non service affecting status level. Priority 3
incident status are generally used for information purposes, to track
upgrades or to track customer’s planned incidents.
Priority 2
A Priority 2 incident means that services are operational but not
within normal parameters (service is active but degraded). Priority 2
implies that protected Lightower provided services are operating in a
linear/non-protected manner or Lightower has provided an
alternative solution to maintain connectivity for the customer.
Priority 1
This is the highest severity level. A Priority 1 incident means that
there is a severe service affecting issue. Customer is no longer able
to conduct business and a alternative solution is not available.
