- Debug log: togglable panel with timestamped, level-tagged, color-coded
entries (error/warning/notice/info/debug) from throughout the app
- Median latency: added to per-host stats and summary (min/med/avg/max)
- Recovery probe: rapid 500ms polling of 4 random hosts when hard offline,
triggers normal tick as soon as connectivity returns
- Health status: multi-level (healthy/slow/degraded/offline) with
hard-offline detection for recovery probe activation
- First tick discarded to avoid DNS/TLS cold-start latency skew
- Added Google, S3 ap-southeast-1 (Singapore) to monitored hosts
- UI: reduced row padding, larger sparkline canvas, bigger axis labels,
pin icon hidden (but space preserved) for local network hosts
- Commit hash shown in footer via vite define plugin
- Add prettier (4-space indents) and reformat all files
- Add Makefile with test/lint/fmt/fmt-check/check/docker targets
- Add MIT LICENSE file
- Add REPO_POLICIES.md
- Fix Dockerfile: listen on 8080 with PORT env var via envsubst
- Restructure README.md with all required sections
- Set up pre-commit hook (make check)
- Update .prettierignore, .gitignore, .dockerignore
SPA for real-time latency monitoring to 10 internet hosts:
- 250ms update interval with 300s history sparkline graphs
- Color-coded latency display (green <50ms to red >500ms)
- HEAD request timing with no-cors mode for cross-origin support
- Built with Vite + Tailwind CSS v4, all dependencies bundled
- Designed for static bucket deployment
