Is Optimism Down Right Now?

Optimism (OP Mainnet) is an Ethereum layer-2 (the original OP Stack) that produces a block every 2 seconds. This page reads Optimism's latest block from a public RPC to tell you whether the network is producing blocks — or whether it's your wallet or a single node that's failing.

Optimism is producing blocks normally — the latest block was just now (based on a public RPC, mainnet.optimism.io).

What “Optimism is down” actually means

Optimism is an OP Stack layer-2 with a single sequencer, so a true Optimism outage is usually a sequencer stall — L2 block production pauses while Ethereum L1 keeps running fine. OP Mainnet has had sequencer incidents that briefly froze the chain. This page reads OP Mainnet's latest block over a public RPC; if the block number stops advancing, the sequencer is the cause, not your wallet or a single RPC.

If Optimism seems down

1
Check status.optimism.io and whether the block height on optimistic.etherscan.io has frozen.
2
A genuine sequencer halt has no RPC workaround — funds are safe on L2 and resume processing once it recovers.
3
If OP blocks are advancing but a dapp fails, switch its RPC endpoint to a fallback (optimism-rpc.publicnode.com).
4
Other OP Stack chains (Base, Zora) run separate sequencers — one being down doesn't mean Optimism is down.
5
Follow @optimism for incident updates.

Frequently asked questions

Is Optimism down right now?
This page reads Optimism's latest block from a public RPC. If the block height shown above is advancing, Optimism is producing blocks and is not down. A frozen, non-advancing height means the chain may be halted; an "RPC unreachable" result means we couldn't reach a node — which can be that node rather than the chain itself.
How does WebsiteDown check if Optimism is down?
We send a JSON-RPC request to a public Optimism endpoint and read the latest block and its timestamp. If it hasn't advanced past a Optimism-specific staleness threshold, we flag it as halted. We don't run a validator, so this is one node's view — confirm with the official status page during an incident.
Is the chain halted, or is it just my wallet or RPC?
Most "is Optimism down" moments are a wallet or a single RPC failing, not the chain. If the block height here is climbing, the network is live — switch your wallet's RPC endpoint. Only a frozen, non-advancing block height points to an actual Optimism halt.
What should I do if Optimism is halted?
There is no user-side fix for a true halt — your funds stay safe on-chain and transactions resume when the network restarts. Follow the official status channels linked above for restart timing instead of repeatedly resubmitting transactions.

Get told when Optimism halts

WebsiteDown can watch Optimism's block height on a schedule and email you if it stops advancing — no need to keep refreshing this page.
