This incident has been resolved.

We are currently investigating an issue affecting Avalanche Mainnet Native RPC, Archive, and Validator services. As a result, some requests to these endpoints may return errors or fail intermittently. A fix has been identified and is being rolled out. We will also be carrying out a brief maintenance window to complete this rollout across the nodes. We apologize for any inconvenience this may cause and appreciate your patience and understanding. We will provide updates as more information becomes available. If you have any questions or concerns, please reach out to your Customer Success Manager.
