  <title>All Sepolia OP-Stack chains: intermittent safe head stalls caused by L1 Sepolia Pectra deposit issue</title>

  <content type="html">
  <![CDATA[
    <p><strong>Type:</strong> Incident</p>
    <p><strong>Duration:</strong> 7 hours and 9 minutes</p>
    <p><strong>Affected Components:</strong> Deposits, Withdrawals, Batch Submission, Transaction Sequencing</p>
    <p><small>Mar <var data-var='date'> 5</var>, <var data-var='time'>07:30:00</var> GMT+0</small><br /><strong>Identified</strong> -
  All OP-Stack chains on Sepolia experience intermittent safe head stalls caused by an issue regarding deposits processing on L1 Sepolia. This is an ongoing situation since the Sepolia Pectra activation at 7:29 UTC and we are monitoring it while client teams work on fixing Sepolia..</p>
<p><small>Mar <var data-var='date'> 5</var>, <var data-var='time'>11:16:00</var> GMT+0</small><br /><strong>Monitoring</strong> -
  The L1 Execution-layer clients are testing and soon publishing releases that fix the identified L1 issue. Official L1 client release communications will follow.

L1 Go-ethereum already has a ready release: &lt;https://github.com/ethereum/go-ethereum/releases/tag/v1.15.5&gt;

L1 testnet node operators are strongly recommended to upgrade to these releases.

The beacon-chain validators of the L1 Sepolia network are expected to deploy the fix in coordination around 2 PM UTC.

After L1 node upgrades and the 2PM UTC deployment the L2 batch-submission issue is expected to resolve..</p>
<p><small>Mar <var data-var='date'> 5</var>, <var data-var='time'>12:58:45</var> GMT+0</small><br /><strong>Monitoring</strong> -
  L1 Sepolia Testnet is expected to update in 1 hour, at 2 PM UTC, to new L1 Execution-Layer Client releases.

It is strongly recommended to update to these releases on Sepolia testnet.

No action is needed on other L1 networks.

Geth: &lt;https://github.com/ethereum/go-ethereum/releases/tag/v1.15.5&gt;

Nethermind: &lt;https://github.com/NethermindEth/nethermind/releases/tag/1.31.4&gt;

Reth: &lt;https://github.com/paradigmxyz/reth/releases/tag/v1.2.2&gt;

Erigon: &lt;https://github.com/erigontech/erigon/releases/tag/v3.0.0-rc2&gt;

Sepolia L1 nodes that do not update are expected to fall out of sync, which may prevent batch-submission and stops L2 nodes from syncing..</p>
<p><small>Mar <var data-var='date'> 5</var>, <var data-var='time'>14:38:56</var> GMT+0</small><br /><strong>Resolved</strong> -
  L1 Sepolia testnet has been updated and is stable again.

For any L1 execution-engine replicas, please update to the releases in the previous status-update, if not already updated.

Batch-submission and syncing of L2 testnets should be stable now that the L1 testnet is stable again..</p>

    <p><small>Jun <var data-var='date'> 20</var>, <var data-var='time'>17:10:29</var> GMT+0</small><br /><strong>Identified</strong> -
  We are currently experiencing elevated fees on OP Mainnet due to high blob fees on L1\. We are mitigating the issue by switching batch submission back to calldata.

While the switch rolls out, users may experience higher fees than normal and the safe head may increase less often due to L1 congestion..</p>
<p><small>Jun <var data-var='date'> 20</var>, <var data-var='time'>17:17:06</var> GMT+0</small><br /><strong>Monitoring</strong> -
  We have performed the switch back to calldata. Users should observe a more stable safe head, as well as lower fees. We will switch back to blobs once the L1 congestion subsides..</p>
<p><small>Jun <var data-var='date'> 20</var>, <var data-var='time'>18:26:00</var> GMT+0</small><br /><strong>Monitoring</strong> -
  Blob data availability fees returned to stability. Batch submission is operational and utilizing blobs again. We will continue to monitor the L1 data fees for changes..</p>

  <title>OP Mainnet degraded performance</title>

  <![CDATA[
    <p><strong>Type:</strong> Incident</p>
    <p><strong>Duration:</strong> 17 days, 9 hours and 12 minutes</p>
    <p><strong>Affected Components:</strong> Node Sync, Transaction Sequencing</p>
    <p><small>May <var data-var='date'> 18</var>, <var data-var='time'>08:10:00</var> GMT+0</small><br /><strong>Investigating</strong> -
  We became aware of a slowdown in the unsafe head of our sequencer today at 09:10 UTC. This impacted other nodes in the network, presenting as an unsafe head stall for approximately 9 minutes. The performance issue resolved on its own after approximately 20 minutes.  
  
We are aware of the root cause and will be issuing further communications in due course. .</p>
<p><small>May <var data-var='date'> 19</var>, <var data-var='time'>13:31:59</var> GMT+0</small><br /><strong>Investigating</strong> -
  We continue to see intermittent degraded performance on the sequencer&#039;s unsafe head..</p>
<p><small>May <var data-var='date'> 19</var>, <var data-var='time'>14:07:01</var> GMT+0</small><br /><strong>Monitoring</strong> -
  The unsafe head is currently performing as normal, however we may still see occasional slow unsafe heads as we roll out performance fixes to the network. We will continue to update this issue if extended periods of slow unsafe heads occur.

No action is required from users..</p>
<p><small>May <var data-var='date'> 21</var>, <var data-var='time'>23:44:48</var> GMT+0</small><br /><strong>Monitoring</strong> -
  We observed another period (approximately 5 minutes) of slow blocks. Block production has resumed and we are continuing to monitor..</p>
<p><small>Jun <var data-var='date'> 4</var>, <var data-var='time'>17:21:37</var> GMT+0</small><br /><strong>Resolved</strong> -
  We have resolved the performance issues on OP Mainnet. The performance issues were a result of transactions with a high I/O cost coinciding with op-geth&#039;s automated background compaction. We have implemented multiple mitigations to avoid such scenarios happening in the future. We will also be upgrading the underlying hardware OP Mainnet runs on in order to provide additional buffer..</p>

<p><small>Jun <var data-var='date'> 6</var>, <var data-var='time'>19:10:01</var> GMT+0</small><br /><strong>Identified</strong> -
  For node operators: 
We have received reports that the [full node Bedrock datadir](https://community.optimism.exchange/docs/useful-tools/networks/#parameters-for-node-operators) 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.

.</p>
<p><small>Jun <var data-var='date'> 6</var>, <var data-var='time'>19:38:02</var> GMT+0</small><br /><strong>Identified</strong> -
  For Archival node operators: While we recommend using the `legacy-geth` archival datadir we upload [once it&#039;s ready](https://community.optimism.exchange/docs/useful-tools/networks/#links), given the size of the archival data disk and the time it&#039;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 &lt;l2geth-rpc&gt;` on `op-geth` and it will forward requests for historical data it can&#039;t handle to `l2geth`..</p>
<p><small>Jun <var data-var='date'> 6</var>, <var data-var='time'>18:20:01</var> GMT+0</small><br /><strong>Identified</strong> -
  The migrated (Bedrock) datadir required to spin up `op-geth` has been successfully hosted and is now ready for distribution.

Full Node Operators are now fully unblocked to spin up.
Archival Node Operators will need to wait for the archival datadir, which may take an additional 5-10 hours.

The datadir can be downloaded from the link found in the OP Mainnet docs: https://community.optimism.exchange/docs/useful-tools/networks/#links.</p>
<p><small>Jun <var data-var='date'> 6</var>, <var data-var='time'>22:48:17</var> GMT+0</small><br /><strong>Completed</strong> -

<p><small>Jan <var data-var='date'> 12</var>, <var data-var='time'>21:04:15</var> GMT+0</small><br /><strong>Identified</strong> -
  The Optimism Goerli migration to the Bedrock release is in its final stages! There were some unexpected delays that we will be addressing to ensure the Optimism Mainnet upgrade takes less time. 

The Optimism Goerli Sequencer has been upgraded to the Bedrock release and is back online at https://goerli-sequencer.optimism.exchange !
Transactions are now being accepted, and we are testing to see that Deposits and Withdrawals are functional.

op-node image is live at: [us-docker.pkg.dev/oplabs-tools-artifacts/images/op-node:v0.10.9](url)

.</p>
<p><small>Jan <var data-var='date'> 12</var>, <var data-var='time'>19:14:09</var> GMT+0</small><br /><strong>Identified</strong> -
  The final blocks on the legacy Optimism Goerli sequencer have been mined and batch submitted to L1. The last block mined was block number 4061223, and the first block of the Bedrock release will be block number 4061224..</p>
<p><small>Jan <var data-var='date'> 12</var>, <var data-var='time'>18:20:58</var> GMT+0</small><br /><strong>Identified</strong> -
  The upgrade to the Bedrock Release of the Optimism Goerli Network has begun!

Transactions to the Sequencer are halted (`eth_sendRawTransaction` RPC calls will be rejected by the Sequencer).

Deposits and Withdrawals are paused.

The Public RPC Endpoint (https://goerli.optimism.exchange/) will stay up with only read access..</p>
<p><small>Jan <var data-var='date'> 12</var>, <var data-var='time'>19:51:27</var> GMT+0</small><br /><strong>Identified</strong> -
  The Optimism Goerli Bedrock upgrade is almost complete.
We are working on spinning the Sequencer back online. Expect final `op-node` and `op-geth` images shortly..</p>
<p><small>Jan <var data-var='date'> 12</var>, <var data-var='time'>18:00:00</var> GMT+0</small><br /><strong>Identified</strong> -
  On January 12 at 1800 UTC, the OP Labs engineering team will begin the work to migrate Optimism’s Goerli Testnet to Bedrock. We expect the migration to take between thirty minutes and 2 hours, during which the Goerli network will be unavailable until the upgrade is complete.

For more information about what to expect on upgrade day, please see the [Upgrade Guide](https://community.optimism.exchange/docs/developers/bedrock/upgrade-guide/)..</p>
<p><small>Jan <var data-var='date'> 12</var>, <var data-var='time'>21:51:50</var> GMT+0</small><br /><strong>Completed</strong> -
  The Optimism Goerli network upgrade to the Bedrock release is complete! 
Deposits, Withdrawals, and transactions to the Sequencer are now back live.

The public `https://goerli.optimism.exchange` endpoint is back up and will resume accepting transactions shortly.

The Optimism Bridge Frontend is still being updated.
