Affected Services and Features:

Google Cloud Networking

Regions/Zones: Multiple regions


Google Cloud Networking experienced packet loss due to transient failures on several fiber paths between two metro locations in the US northwest region and US central region. This packet loss led to disruption of traffic between multiple cloud regions globally. Most of the transient failures were cleared by 25 March 2022, 00:08 US/Pacific mitigating the issue for global regions.

An unrelated transient fiber failure in the Asia region caused an additional minor disruption that was limited only to the APAC region between 25 March 2022 00:10 US/Pacific and 25 March 2022 00:16 US/Pacific.

Customer Impact:
