No incidents recorded
When a mining pool goes down, your ASIC hardware continues consuming electricity but earns nothing. Even brief outages can cost miners significant revenue, especially at scale. Independent uptime monitoring helps you identify the most reliable pools and avoid those with recurring availability issues.
HashRadar checks each pool's Stratum endpoint every 5 minutes using a full mining protocol handshake: we send mining.subscribe followed by mining.authorize, just like a real miner connecting to the pool. This proves the pool is not only reachable but actively serving mining work. We also monitor HTTP endpoints (websites and dashboards) for web availability.
Our incident state machine requires 3 consecutive failed checks (15 minutes) before declaring a pool down, preventing false alarms from transient network issues. Recovery requires 2 consecutive successful checks. This approach balances sensitivity with reliability, giving you accurate uptime percentages you can trust.
