Update timeline

  1. identified Jul 19, 2026, 01:21 AM UTC

    We have identified the issue causing the degraded performance on our BSC Mainnet nodes in London region. Elevated response times are expected for `eth_getLogs` calls. The root cause has been traced to a resource exhaustion. We are currently working on mitigation strategies.

  2. resolved Jul 19, 2026, 05:11 AM UTC

    We implemented a fix by adding more capacity, and things have stabilized. The incident has been resolved.
