Duration: 1 hours, 41 minutes

Affected Services and Features:

Regions/Zones: europe-west2-a

Description:

Google Cloud Networking and Google Cloud Load Balancing (GCLB) experienced elevated packet loss in europe-west2-a. From preliminary analysis, the root cause of the issue is a configuration change on a device that caused a permission issue with an automatic configuration deployment and failed to propagate. This resulted in a corrupted configuration which caused traffic to be dropped.

Cloud Interconnect in europe-west2 observed an increase in packet loss. Cloud Spanner requests passing through europe-west2-a experienced increased error rates.
