Update timeline

  1. investigating May 16, 2026, 01:28 AM UTC

    We are currently investigating degraded performance on Ethereum Sepolia. Block production has been intermittent, with the chain's head advancing unevenly. This appears to be a network-wide issue. Alchemy's infrastructure is operating normally and we do not currently anticipate customer-facing impact. We will continue to monitor and provide updates as we learn more.
