cost-calc.js (FIXED)
Bandwidth / traffic / 95th-percentile billing calculator (zero-dependency Node.js): port ↔ monthly traffic conversion, P95 computation, and a three-way price comparison across flat port, 95th-percentile and peak billing, with a recommendation. Works as a CLI and as a module.
mtr-report.py
MTR report parser and evidence generator: feed it `mtr --report` output, get structured JSON plus a Markdown evidence file, with automatic flagging of "sustained loss at the final hop" and "suspected ICMP rate limiting on an intermediate hop" — a ticket-ready package in one step.
first-hour-init.sh
Idempotent first-hour initialization script: five stages — SSH hardening, firewall baseline, fail2ban, automatic security updates, baseline capture — running it ten times gives the same result as running it once. Debian/Ubuntu; usage and extension notes included.
Why datacenters are called HKG, SIN and NRT
A short piece on naming: how the IATA airport-code system got borrowed by hosting, the logic behind cloud vendors' Region/AZ naming, where the Tier classification comes from — and why our speed-test tool names nodes with airport codes.
A latency investigation, written as a log
One "the site got slow" investigation written as a timestamped log: from user report to MTR localization to a closed ticket. The data is a teaching example (labelled as such); the narrative structure drops straight onto your own incident reviews.
What is a server? A 1,000-word explainer (AI draft + human review)
An explainer for readers with zero background: a server is a computer that never gets switched off — the differences are reliability engineering, where it lives, and how it is managed. Drafted by a language model and reviewed paragraph by paragraph by a human; the review log is appended at the end.
cost-calc.js
带宽/流量/95 计费计算器（Node.js 零依赖）：端口↔月流量换算、P95 计算、包月/95 计费/峰值三模式比价，输出决策建议。CLI 与模块两用。
mtr-report.py
MTR 报告解析与存证脚本：吃进 mtr --report 输出，吐出结构化 JSON + Markdown 存证档案，自动标注「末跳持续丢包」与「中间跳限速疑似」，工单提交一步到位。
first-hour-init.sh
上架首小时幂等初始化脚本：SSH 加固、防火墙基线、fail2ban、自动安全更新、基线采集五段式，跑十遍与跑一遍结果相同。Debian/Ubuntu 口径，附用法与扩展说明。
机房命名的行业习惯考
为什么机房叫 HKG、SIN、NRT？一篇关于命名的考据小品：IATA 机场代码的借用史、云厂商 AZ 命名法、Tier 分级的由来——以及为什么本站测速工具选了机场代码体系。
一次延迟排查的记录体写作
把一次「网站变慢」的排查写成带时间戳的记录体：从用户反馈到 MTR 定位到工单闭环。数据为教学示例（已标注），叙事结构可直接套用于你自己的故障复盘。
《服务器是什么》千字科普（AI 写作 + 人工审校）
给完全零基础读者的千字科普：服务器就是一台不关机的电脑，差别在可靠性设计、网络位置和管理方式。AI 起草、人工逐段审校的示范样本，审校记录附文末。
