Unsafe Head Stall on Mainnet

We are reopening this incident after reports of additional instability.

Our team has resolved the unsafe head stall. If you continue to experience an issue, please let us know on Discord.

We are investigating reports of an unsafe head stall on OP Mainnet.

We have identified the cause of the unsafe head stall and have applied a fix. At this time node operators may observe a single-block reorg of the unsafe chain. Chain sync should be back to normal at this time.

We have observed both the safe and unsafe parts of the chain advancing. At this time the network is fully operational. We will continue monitoring the situation.

We have identified a potential root cause of the unsafe head stall. At this time the network is functional, however until the fix is fully rolled out the possibility of continued instability remains. We will continue to update this page as the fix rolls out.

We are continuing to roll out a potential fix for the unsafe head stall. At this time no action is required from users or node operators. We will continue to update this page as the fix rolls out.
