Data / Fleet uptime, measured / 2026
The share of time our hosted machines were hashing, and the capacity-weighted version that counts a machine at half speed as half up.
Fleet uptime (hashing at all) opened 2026 at 100.0% (March 25, 2026) and closed at 85.8% (September 21, 2026), down 14.2%. The high was 100.0% on March 25, 2026 and the low 54.1% on July 14, 2026.
| Month | Month end |
|---|---|
| March 2026 | 100.0% |
| April 2026 | 94.3% |
| May 2026 | 86.2% |
| June 2026 | 77.0% |
| July 2026 | 81.1% |
| August 2026 | 95.0% |
| September 2026 | 85.8% |
Every machine we host reports its hashrate every five minutes. Uptime is the share of those readings that showed any hashing at all, across every machine reporting that day. Load counts each reading as the machine’s hashrate over its rated hashrate, capped at 100%, so a machine running at half speed counts as half up.
