What happens if a mining pool goes offline?

If your mining pool goes offline, your miner cannot send it work or receive new mining jobs, so you usually stop earning through that pool until the connection returns. Your Monero wallet is not affected, but any rewards the pool has not yet paid you may be delayed—or lost if the pool never comes back.

What happens to your mining session

A mining pool combines work from many miners and shares the rewards. Your miner gets a job from the pool, then sends back shares: small proofs that your device has done mining work.

When the pool becomes unreachable, your miner may:

• Show connection errors or repeated reconnect attempts.
• Keep working briefly on its last job.
• Pause until it can get a new job.
• Switch to a backup pool, if that feature is supported and configured.

A browser miner can also lose contact with an intermediate server that connects your browser to the pool. From your side, that can look like a pool outage even when the pool itself is working.

Your browser may still show CPU activity or a mining speed. That does not prove you are earning. Check for accepted shares, meaning work the pool has received and credited. Work done during a disconnection is not reliably saved for payment later.

What happens to your unpaid rewards

Monero already received in your own wallet stays there. A pool outage cannot take those coins back.

Your unpaid pool balance is different. It is a record kept by the pool, not money already held in your wallet. If the outage is temporary and the pool’s records are intact, that balance will usually still be there when service returns.

Payouts can be delayed because:

• The pool’s payment system is offline.
• Your balance is below its minimum payout amount.
• Rewards from recently mined blocks are still locked. Newly mined Monero needs 60 blocks before it can be spent—roughly two hours at the usual block time.

If the pool shuts down permanently, whether you receive your balance depends on its operator, available funds, and final payout policy. Payment is not guaranteed.

What happens when the pool returns

Your miner may reconnect automatically, but you should check rather than assume. Some browser miners need you to reload the page or restart the mining session.

Look for a working connection and newly accepted shares. Your account balance or statistics may take longer to update than the mining connection.

You generally do not receive extra payment to make up for the downtime. However, rewards for work accepted before the outage may appear later. The outcome depends on the pool’s reward rules; some use a rolling window of recent shares when dividing block rewards.

What you can do during an outage

First, check whether only the dashboard is down or mining connections have also stopped. A broken statistics page does not necessarily mean mining has stopped.

Then:

• Check the pool’s status notices and your own internet connection.
• Pause mining if your device is consuming power without submitting accepted shares.
• Use a reputable backup pool if your miner supports one.
• Keep your payout address and recent balance records.

Never share your wallet’s recovery words or private keys with anyone claiming they can “restore” a pool payout.

The bottom line

A pool outage mainly interrupts accepted work and payouts. Coins in your wallet remain safe, while unpaid pool rewards depend on the pool recovering and honoring its records. Check accepted shares—not just mining speed—to know whether your device is doing useful work.
