HKMA OR-2: the evidence pack your board needs before May 2026
A pragmatic checklist for banks and their outsourced data-center providers — mapped to severe-but-plausible scenarios, tolerance for disruption, and third-party dependency mapping.
Liquid Cooling Is Table Stakes. Reliability Isn't.
Everyone will have coolant loops. Few will have failure-mode libraries for them.
Commissioning liquid-cooling CDUs without breaking your reliability envelope
Field notes from three AI-density retrofits in Tseung Kwan O and Tsuen Wan — where the failure modes live, and the six telemetry points we now insist on before energisation.
From 5–15 kW to 40 kW+: How to Rank What Breaks First in a Density Retrofit
A density retrofit without an ACR refresh is a calendar of unplanned outages.
When Clusters Act as One Fabric, Failures Cascade Across Sites
AI DCI turns two sites into one blast radius. Model it before it bites.
BEEO 2026: what actually changes for data-hall operators in September
The Buildings Energy Efficiency Ordinance amendments take effect in September. Here's the operator-level impact — PUE reporting cadence, verification, and where the audits will focus.
BEEO 2026 Meets AI Density: Why Energy Audits and Reliability Belong Together
The audit will happen. Use it as the anchor for the reliability work you already owe your board.
Vacancy Tightened. Quality Split. Why Legacy Halls Need a Different Playbook
Premium AI-ready capacity fills; legacy space competes on reliability, not sticker.
Power Is the Binding Constraint. Reliability Is How You Stretch What You Have
You can't build your way out of CLP capacity. You can engineer your way to more effective MW.

Stop Buying AI Capacity. Start Buying Lifecycle Decisions.
Capacity is a moment. Lifecycle is a decade. Price accordingly.
Field note: the UPS battery drift we found on a 2019 install
A quarterly asset review surfaced a 14% capacity drift across one string that the manufacturer's monitoring flagged as healthy. Here's how we caught it and what the operator did next.
