Optimism will upgrade the infrastructure of the Kubernetes mainnet on January 27, with an expected downtime of less than 15 minutes

ChainCatcher message, Optimism will perform some necessary upgrades to the infrastructure of the Kubernetes mainnet on January 27, with expected downtime not exceeding 15 minutes.

It is reported that the Optimism team discovered early this morning that an earlier service provider interruption triggered an error in the Optimism node, leading to a decline in the performance of the Goerli testnet. The team has now deployed a fix for the Goerli testnet and is monitoring the results. If users are running an archived Optimism Goerli node, no action is required. If users are running a full node, they need to resynchronize the node from the migrated Bedrock Goerli data directory. (Source link)
