Lodestar Public services
Lodestar Public RPC endpoints
The infra team runs and maintains publicly advertised archive CL nodes. Archive CL nodes are beacon nodes started without the checkpointSyncUrl flag.
Public nodes belong to the [public] ansible group.
The nodes are attached to the Lodestar loadbalancer in the Lodestar Scaleway project.

Checkpointz servers
We currently have entries on the community-maintained list of Ethereum Beacon Chain checkpoint sync endpoints. The Checkpointz servers rely on the public archive nodes to serve state.
