On October 22, 2024, at 23:48 UTC, a network issue in our Osaka (jp-osa) region impacted Object Storage availability, resulting in 503 errors for some users. Full service was restored by 00:36 UTC on October 23, 2024. The disruption was traced to connection queues reaching capacity due to elevated latency.
In response, we stabilized access by clearing the queues. To prevent similar issues in the future, we’re enhancing system settings to improve logging during latency spikes and refining protocols to accelerate issue detection and response.
This summary provides an overview of our current understanding of the incident given the information available. Our investigation is ongoing and any information herein is subject to change.
