Which Monero pools have the best uptime?
The Monero pools with the best uptime are the ones you can verify are consistently reachable from your location—not simply the biggest pools. SupportXMR and MoneroOcean are established names worth checking, while P2Pool offers a different kind of reliability by avoiding a single central pool server; without current monitoring data, you should not treat any of them as a proven uptime winner.
Which options should you check first?
Your shortlist can include these three options, but they work differently:
- SupportXMR: A conventional Monero pool, where a central operator runs the service that coordinates your mining. Check its current connection instructions, any maintenance notices, and recent reports of connection problems.
- MoneroOcean: An established service that pays in XMR and supports switching between mining algorithms—the calculations used to mine different coins. For your purposes, check whether the specific endpoint and mining setup you plan to use stay connected reliably.
- P2Pool: A decentralized pool, meaning there is no single pool operator or central pool server that everyone depends on. This removes one common failure point, but your own software, Monero node, and internet connection still need to stay online. A node is software that checks and shares blockchain data.
These are starting points for investigation, not a measured ranking. Pool availability can change, and an older reputation does not prove excellent uptime today.
What counts as good pool uptime?
For mining, uptime means the pool keeps sending your miner work and accepting valid results. Those results are called shares: small proofs of work used to track your contribution.
A pool website can stay online while its mining servers are unavailable. The reverse can also happen. That is why checking only the homepage tells you very little.
Look for evidence covering several weeks or months:
- Mining-server availability, rather than website availability alone.
- Incident history, including how long outages lasted.
- Regional connection options and clearly documented backup servers.
- Reports from multiple miners, not just one glowing review.
Be cautious about “100% uptime” claims with no stated measurement period or independent evidence.
Test reliability from your own connection
The best pool for someone elsewhere may not be the most reliable one for you. Your internet provider, distance from the server, and network routing can all affect the connection.
Try your shortlisted pools with the same device and similar settings. Watch for:
- Repeated disconnects or connection timeouts.
- Long periods without new mining work.
- Rejected shares or stale shares, which arrive too late to count.
- Whether your miner reconnects automatically after a brief interruption.
Rejected shares do not always mean a pool outage. Device settings and connection delays can also cause them.
If you mine through a browser service, check whether it lets you choose a pool at all. Your connection may depend on that service’s own gateway—a server between your browser and the pool. Excellent pool uptime cannot fix an unreliable gateway.
The bottom line
Start by comparing SupportXMR and MoneroOcean using current operational evidence, and consider P2Pool if you want to avoid dependence on a central pool server. Choose based on sustained mining connections from your own setup, not pool size or advertising. Where your miner supports it, configure a trusted backup pool so one outage does not leave you idle.
