Scheduled

We will perform an urgent upgrade of Base Mainnet and Sepolia node-reth infrastructure to v0.16.1 today at 11:00 UTC.

This release is required for pruned node operators and updates the base-consensus and base-reth-node dependencies to v0.9.1.

No downtime is expected, but customers may experience brief connection interruptions and a small number of HTTP 503 responses as services restart and resynchronize with the network.
