Stakeworld offers a high availability infrastructure for RPC nodes and bootnodes. We also try to share our experiences as much as possible on the polkadot wiki.

This is a request for funding of:

• Setting up and maintaining high availability RPC services for polkadot and polkadot commons (AssetHub, BridgeHub and Collectives).
• Setting up and maintaining a bootnode for polkadot.

The full proposal can be found here.
