Network Impact Guidelines

GRNOC Network Impact Guidelines

Network Impact is an objective scale of measure used internally to quantify the highest level of impact to the network that occurred throughout the duration of a problem or maintenance. Network Impact seeks to answer, “How severe is the problem/maintenance to the network?”

1-CRITICAL

  • The network, a portion of the network, or a key network resource, has failed causing an outage of service.
  • The network, a portion of the network, or a key network resource, is severely degraded rendering the network nearly unusable.

2-HIGH

  • The network, a portion of the network, or a key network resource, has failed or is severely degraded, but service has not been affected due to redundant resources.
  • The network, a portion of the network, or a key network resource, is experiencing mild-to-moderate degradation, and service is affected.
  • Security requests and incidents.

3-ELEVATED

  • Network problems or maintenances of limited scope that pose no risk to the network as a whole.
  • Direct connectivity to a single entity (peer, connector, lambda) has been lost.
