On 25 July 2025 from 19:06 UTC to approximately 21:14 UTC, Wasabi's eu-west-3 (London) region experienced a service incident which resulted in elevated HTTP 5XX errors being returned for many request types to the region. The cause for the incident was an internal service failure, which prevented multiple services within the region from being able to successfully communicate across platforms. Due to this failure, our internal proxy service was unable to efficiently direct requests within the region, resulting in a degradation of the service and causing client requests to fail. Wasabi's Engineering and Operations teams worked to systematically restart impacted service hosts beginning at 19:20 UTC through 19:28 UTC. Once the hosts were back online, internal routing issues due to faulty configuration files required the team to manually correct the configurations and apply those to service hosts. By 21:24 UTC, all hosts and services were operating properly, and the region was operational.
