Date/Time of the Issue (All time US/Pacific)

Incident Start: 18 August 2026 16:58
Incident End: 19 August 2026 05:40
Duration: 12 hours, 42 minutes 

Summary

On August 18, 2026 from 16:58 to August 19, 2026 05:40 US/Pacific, Drive customers in Australia, Philippines and New Zealand experienced degraded performance and slowness. During this period users also experienced 502 errors. Other Google Workspace services were not affected. 

Preliminary Root Cause

Google utilizes a multi-tiered global load balancing and network routing architecture to serve traffic efficiently. To ensure fair use and prevent congestion, bandwidth allocation is managed by attributing traffic to specific downstream services.

A misconfiguration in the attribution of traffic caused the bandwidth usage to be incorrectly attributed to the frontend network load balancing tier itself, rather than to the Drive service.

The sequence of events leading to customer impact was as follows:

• Traffic from the regional load balancing tier was incorrectly attributed to the load balancing infrastructure rather than the Drive service.
• Unrelated traffic caused network bandwidth usage attributed to the load balancing infrastructure in this region to exceed its quota.
• Network bandwidth management systems applied throttling to this traffic to enforce quotas, causing severe network congestion affecting Drive traffic in this region.
• This congestion led to increased latency, slowness, and error rates for users accessing Drive in the affected regions.

Remediation 

Google engineers were alerted to the issue via automated monitoring and an influx of customer support cases, with initial incident response teams engaged by 17:21 US/Pacific on August 18, 2026.

Engineers initially attempted to alleviate the congestion by draining regional frontend traffic to an alternate geographic location, but this proved ineffective and was reverted. The team then mitigated the issue by migrating regional traffic to an upgraded internal network routing architecture, which correctly set the traffic attribution for Drive.

Normal operations were fully restored once 100% of the regional traffic was migrated to the upgraded network architecture.

Description of Impact

Between August 18, 2026, at 16:58 US/Pacific and August 19, 2026, at 05:40 US/Pacific, Google Drive users in Australia, Philippines and New Zealand experienced severe latency, degraded performance and 502 errors.

During this roughly 12-hour and 42-minute window, affected customers may have observed significant slowness or errors when attempting to access Google Drive or listing files through Editors (e.g. docs.google.com), with initial load times significantly delayed. The issue was fully mitigated as of August 19, 2026, at 05:40 US/Pacific, and normal service has been restored.

Summary

Multiple customers in Australia and New Zealand may have experienced slowness or errors while accessing Google Drive.

Description

The issue with Google Drive has been resolved for all affected customers as of Wednesday, 2026-08-19 05:40 PDT.

Our engineering teams determined the slowness was the result of a localized capacity and routing issue within our regional infrastructure.

To restore service, we implemented a fix to alleviate the network congestion and accelerated a planned infrastructure upgrade in the affected region to ensure normal performance levels.

We thank you for your patience while we worked on resolving the issue.
