These numbers come from this server's p2pool node. If that service goes down, or if the Defcoin node stops updating, the warning banner above will say so.

Global Pool Hashrate means everyone mining in the wider p2pool pool. Local Pool Hashrate means only miners pointed at this DC903 server. Network Hashrate means the whole Defcoin network, not just p2pool. When mining is quiet, this page shows inactive labels instead of pretending old numbers are still current.

Checking recent pool activity.

P2Pool share counters are not blockchain orphaned blocks. Orphaned shares are P2Pool sharechain shares that lost a sharechain race. Dead/stale shares are shares received too late, or shares that no longer build on the current P2Pool sharechain tip.

The explorer's orphaned-block list is different: it records parent-chain blocks that were replaced by a competing Defcoin chain with more accumulated work. See blockchain orphan/reorg explanation.
