Uptime & Boot Reliability Assessment
Flagship 72-hour evaluation of cold starts, warm restarts, and sustained hash rate for miners at 0.05 TH/s and above.
Who this is for
Hosting operators in Ulsan and neighbouring provinces who need documented evidence before placing used or refurbished miners into unattended rows. Buyers negotiating bulk purchases who want independent boot-cycle data rather than manufacturer claims alone.
What is included
- Three cold-start sequences from fully powered-off state
- Six warm restarts after controlled shutdown
- Simulated brief power dip (client-approved, on protected circuit)
- Continuous hash rate logging for 72 hours at rated wattage
- Intake and exhaust temperature readings every 15 minutes
- Fan speed response notes during thermal load
- Plain-language verdict: suitable for unattended / requires monitoring / retire
What is excluded
- Pool configuration or firmware modification
- Repair or parts replacement
- Electrical work beyond standard PDU connection
- Hash rate optimisation or overclocking attempts
Process
- Intake call — You describe the miner model, serial range, and deployment context.
- Scheduling — We agree a window at your site or our Nam-gu assessment bench.
- Observation — 72-hour logged run with defined boot-cycle protocol.
- Report delivery — PDF within five business days, including CSV boot log.
Provider
Assessments are conducted by Service Ashfield field technicians with experience across Antminer, Whatsminer, and Avalon units common in Korean hosting rooms.
Preparation
Ensure the unit is accessible, labelled with serial number, and connected to a circuit that can be switched without affecting unrelated racks. Provide model name and rated TH/s from purchase documentation.
