On December 13, 2022, at approximately 02:12 UTC, we identified an issue with a component in our Japan Google Cloud Platform environment. As a result, customers in that environment were unable to make changes to their models.

Initial findings identified that the issue was caused by a significant increase of log generation, resulting in a component performance degradation. To resume service, we implemented a workaround by reconfiguring the component, while we continue to investigate a permanent fix. Service was restored at 03:32 UTC.

To avoid a reoccurrence, we continue to examine the root cause, to identify an appropriate configuration for the component and to reduce the volume of logs being generated. In the interim, we have completed a review of other similar components to ensure that they are healthy. We have also added supplemental monitoring to provide forewarning, so that we can take the appropriate action to mitigate impact.

We deeply apologize for the impact this had on your business operations. We understand the disruption these issues can cause to your business and users, and we are continuously strengthening our systems and procedures to avoid similar issues from happening again in the future.
