Optimism - Notice history

Our team has resolved the Optimism Goerli safe & unsafe head hatl, and transaction sequencing should now be fully operational for all users. If you continue to experience an issue, please let us know on Discord.

Thanks for your patience with us!

L1 has started finalizing again, and the network should now be fully operational for all users. If you continue to experience an issue, please let us know on Discord.

Thanks for your patience with us!

Our team has implemented a fix to mitigate the instability on L1, and is monitoring the situation.

We’ll post an update as soon as the issue is fully resolved. At this time, syncing from L1 and withdrawals should be operational.

Our team has identified the cause of the batch submitter lag, and is actively working on a fix.

This appears related to ongoing finality issues on Ethereum mainnet.

At this time, users syncing from L1 will experience delays receiving blocks and users attempting to post withdrawals will experience delays until our backlog of state proposals clears.

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

Our team has resolved the safe head halt, and the Optimism Goerli network should now be fully operational for all users. If you continue to experience an issue, please let us know on Discord.

Thanks for your patience with us!

Our team has identified the cause of the slow safe head progression & safe head halt, and has deployed a fix.

The issue is the result of unusually high throughput on Optimism Goerli with which the batcher couldn't temporarily keep up given its current configuration. We tweaked the configuration and expect the safe head to catch up soon.

At this time, user will continue to experience a safe head halt or slow safe head progression.

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

Our team has resolved the block production stall. Nodes should be able to fully sync for all users. If you continue to experience an issue, please let us know on Discord.

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

One of our read-only replicas failed, which caused requests for newly created blocks from the sequencer to fail. The sequencer itself was unaffected.

At this time, node operators may continue to experience instability as we recover the failed replica.

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

Our team has resolved the issue with legacy withdraws. You should be able to use the bridge interface normally. If you continue to experience an issue, please let us know on Discord.
Thanks for your patience with us!

The bridge interface for Goerli is working again for new withdraws and withdraws issued after February. For withdraws initiated before February we are still investigating.

Thanks for your patience with us!

Our team has implemented a fix to resolve the head halt, and is monitoring the situation. No action is required on the part of replica operators. Nodes should automatically come back in sync as new data is posted to L1.

We’ll post an update as soon as the issue is fully resolved.

Our team continues to investigate the head halt on Goerli. While we are seeing the network start to recover, block production is still degraded.

We’ll continue to update you here.

This incident has been resolved as of 3/15 already.

We are resolving this incident. Please watch our Twitter for updates once we have published a fixed op-node release and node operators can remove the temporary flag.

We have publicly shared the immediate fix to solve the issue for node operators on Optimism Goerli. Major services and infrastructure that operate Optimism Goerli nodes are slowly starting to resume operations as they add the specified flag.

We will post an update when we have published a fixed op-node release and node operators can remove the temporary flag.

The sequencer is confirmed to be up and processing transactions, deposits, and withdrawals safely. All nodes serving the public RPC endpoint have been updated with the below flag.

Our team has identified the cause of the Optimism Goerli node halts.

With the L1 Goerli network upgrading to Shapella, a change during Shanghai was made to how the block hash is derived. We have checks inside the op-node to recompute the block hash to ensure your L1 RPC is being honest - these started failing with the Shanghai updates.
This will prevent any nodes being operated on Optimism Goerli from continuing to produce new blocks. The sequencer is confirmed to be up and processing transactions, deposits, and withdrawals safely.

If you operate nodes on Optimism Goerli:

To immediately fix this issue, please add a flag:
--l1.trustrpc=true
or
OP_NODE_L1_TRUST_RPC="true"
to disable these block hash checks.

We will be pushing a new release of the op-node in the coming days with a fix. After upgrading to that new release you will be able to remove the above flag.
