Investigating

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.
