Open Question: Can Availability Reach Data-Center Uptime?
Whether a burner can ever meet hyperscale Tier III uptime is unanswered; today the model is 30 to 100x short.
The question
Can a fusion machine reach 0.99982 availability? Modelled Aegis availability is 0.86–0.995, a 30–100x downtime gap. No fusion machine has the operating hours to answer this, so it is genuinely open — and we do not pretend otherwise by selling Aegis as a sole Tier-III source today.
What would change the answer
- Fleet operating hours that expose and remove failure modes
- Component lifetimes measured under the 5.44% neutron load
- Redundancy that turns single-point failures into ride-throughs
- Predictable, planned maintenance replacing unplanned outages
Honest posture
The credible near-term claim is improving, characterised availability paired with grid or storage — not a Tier-III guarantee. Whether the gap fully closes is a question only operating fleets can answer.
No fusion machine has the operating hours to answer whether Tier III uptime is reachable, so we decline to answer it in advance.

Whether the 30–100x gap ever fully closes is a question that only operating fleets can settle, and we present it as open rather than solved.
