Extended Story: Ansan Co-Location Row
A 140-worker GPU row in Ansan was losing pool shares every afternoon despite stable hash on the dashboard. Our assessor traced a management VLAN loop through a spare switch port left enabled. The written report included switch CLI snippets the client’s technician applied overnight. Shares stabilized within 48 hours. The manager noted our photos of cable dress made landlord insurance renewal simpler — visual proof of orderly installs.
Extended Story: Bupyeong Shed Expansion
Before adding 40 new ASICs, a Bupyeong operator wanted proof the existing 63A feed could handle summer load. We logged phase balance and thermal rise during a July visit. The report recommended staggered energizing rather than a full panel upgrade — saving roughly ₩2.1M in quoted electrical work. They still upgraded ventilation, which we flagged as the real bottleneck.
Testimonials
The hash spreadsheet matched what our pool showed — finally. I appreciated that they listed which workers were throttling before we blamed the ISP.
— Young-seok R., 92-worker shed, Incheon
Report arrived on day four as promised. A few photos were blurry near the ceiling fans, but the switch diagram was clear enough for our electrician.
— Eun-ji M., warehouse leaseholder, Siheung
Monitoring setup took longer than the brochure suggested because our old routers needed replacing first. They were upfront about that on the follow-up call — no surprise invoice.
— Tae-woo B., remote operator, Goyang
We only needed the networking sketch, not the full assessment. They honored a reduced scope without pushing the bigger package.
