Google Cloud Storage experiences 12.5 hours of write errors in us-central1: what it reveals about hidden dependencies
On 8 October, Google Cloud Storage experienced high latencies and error rates on uploads and writes in the us-central1 (Iowa) region for 12 hours and 30 minutes. Google published its preliminary report on 9 October, acknowledging that there was no workaround.
News summary
According to the preliminary report published by Google on its status dashboard, on 8 October 2023, Google Cloud Storage experienced high latencies and error rates on upload and write operations in the us-central1 (Iowa) region. The incident lasted 12 hours and 30 minutes; a minor portion of reads was also affected.
Google indicated during the incident that no workaround was available and has announced a final report with preventive measures once its investigation is complete.
Although the region is in the United States, the impact is not limited to North American companies. Many SaaS applications used by Spanish companies store files, backups, or logs in that region without the customer knowing. When it fails, users find their billing tool, CRM, or document management system is unable to save.
The key takeaway is to understand your dependencies: not only which cloud provider your company uses, but also which providers and regions your critical applications rely on, and what to do if they stop accepting writes for half a day.
