We have updated our estimated impact to an average of 2% and a peak of 3.6% GCS global error rate, based on a more thorough review of monitoring data and server logs. The initial estimate of impact was based on a internal assessment hosted in a single region; subsequent investigation reveals that Google's redundancy and rerouting infrastructure worked as intended and dramatically reduced the user-visible impact of the event to GCS's global user base. The 2% average error rate is measured over the duration of the event, from its beginning at 11:05 PST to its conclusion at 12:24 PST.

The issue with Google Cloud Storage error rates has been resolved for all affected users as of 12:30 US/Pacific. We will conduct an internal investigation of this issue and make appropriate improvements to our systems to help prevent or minimize future recurrence.

The issue with Google Cloud Storage in the US regions should be resolved for the majority of users and we expect a full resolution in the near future. We will provide another status update by 2018-01-25 13:00 US/Pacific with current details.

We are experiencing an issue with Google Cloud Storage beginning Thursday, 2018-01-25 11:23 US/Pacific. Current investigation indicates that approximately 100% of customers in the US region are affected and we expect that for affected users the service is mostly or entirely unavailable at this time. For everyone who is affected, we apologize for the disruption. We will provide an update by 2018-01-25 13:00 US/Pacific with current details.
