On May 22, 2025 from 00:12 to 02:54 UTC Storj experienced a service disruption causing elevated error rates and increased request latency that affected the US1 API, Gateway, Linksharing, and US1 - Select services. We discovered lock contention triggered by high-load delete operations. In the short term, we are artificially slowing down some of these intensive requests to leave needed headroom. We will eliminate the lock contention going forward.
