On Monday, August 28th at 17:00 UTC, we are upgrading the OP Mainnet sequencer deployment configuration to enable future zero downtime deployments. As part of this planned maintenance, users can expect up to five minutes of downtime on OP Mainnet.

We’ll update this status once the maintenance window is completed and OP Mainnet is fully operational on https://status.optimism.io/

OP Goerli is no longer experiencing node halts, which were caused by the L1 Goerli testnet reorg. As shared in the previous status, full node operators do need to take one of the following actions:
1. Delete Geth’s datadir, then replace it with the fully-synced archival database available from https://datadirs.optimism.io/goerli-bedrock-archival-2023-07-29.tar.zst.
2. Make a call to eth_getblockbynumber with finalized as the block tag. Then, roll the full node back to that block value + 1 using debug_setHead.
3. Resync the full node from a backup prior to block 12572500, or from genesis.
This issue is resolved and we will be sharing a full post-mortem when ready.

We have identified the root cause of this issue.

The L1 Goerli testnet experienced a large reorg of approximately 18 blocks. In addition to the large reorg, a significant number of blocks were missed, resulting in one large reorg and many missing blocks. This caused a large (>256 block) reorg on OP Goerli. Currently, users operating full nodes on OP Goerli will experience a node halt. These nodes will not sync new blocks from the OP Goerli network, and may return inconsistent data over RPC. Users operating archival nodes on OP Goerli are not affected and we do not expect this issue to occur in any capacity on OP Mainnet.

To resolve this issue, full node operators need to perform one of these actions:
1. Delete Geth’s datadir, then replace it with the fully-synced archival database available from https://datadirs.optimism.io/goerli-bedrock-archival-2023-07-29.tar.zst.
2. Make a call to eth_getblockbynumber with finalized as the block tag. Then, roll the full node back to that block value + 1 using debug_setHead.
3. Resync the full node from a backup prior to block 12572500, or from genesis.
We apologize for the inconvenience and will share a full post-mortem when ready.

Our team has identified the cause of the safe head stall, and is actively working on a fix.

The issue is the result of an improperly closed channel. This is a known issue with the batcher, and will most likely resolve itself within the next hour.

At this time, users syncing the safe head only will continue to experience delays receiving new blocks until a new batch is posted.

Please wait while the improperly closed channel automatically expires.

We’ll continue to share updates as we have them.

We narrowed down the issue to a problem submitting a batch to L1. These issues typically resolve themselves within an hour.

We’ll continue to update you here.

For Archival node operators: While we recommend using the legacy-geth archival datadir we upload once it's ready, given the size of the archival data disk and the time it'll take for it to become available (up to 24 hours), we recommend preserving your legacy archival nodes and routing archival traffic to them if possible. To check if your legacy archival node is able to serve traffic, please do the following:
Verify that the head block number is 105235062
Verify that the head block hash is 0x21a168dfa5e727926063a28ba16fd5ee84c814e847c81a699c7a0ea551e4ca50
If both of these criteria are true, then your legacy archival node is on the same block as the archival datadir and can be used to serve user traffic.

You can set --rollup.historicalrpc <l2geth-rpc> on op-geth and it will forward requests for historical data it can't handle to l2geth.

For node operators:
We have received reports that the full node Bedrock datadir is taking a long time to download. Since it is available on GCS, you can use parallel downloader tools like aria2 to make it faster. This method has seen download speeds in excess of 100MB/s. Some recommendations:
- Run the download on a high-network box in the cloud.
- Use aria2 or the gcloud storage cp command to download the file in parallel.
