Telegram DC Latency Monitor 🌐⚡️

A modern, framework‑free website to monitor latency to Telegram datacenters with a premium glassmorphism UI, responsive layout, and instant country code search.

Features ✨

• DC latency via HTTPS (median from parallel requests) with fallback to WebSocket
• Auto refresh every 5s with animated countdown and status transitions
• Real‑time country search (code like AT, +43, 43, partial numbers)
• Glassmorphism design, dark/light theme with persistence
• Mobile‑first responsive grid and smooth animations
• Accessibility: ARIA labels, keyboard navigation, live regions

Datacenters 🛰

• DC1 Pluto: wss://pluto.web.telegram.org/apiws
• DC2 Venus: wss://venus.web.telegram.org/apiws
• DC3 Aurora: wss://aurora.web.telegram.org/apiws
• DC4 Vesta: wss://vesta.web.telegram.org/apiws
• DC5 Flora: wss://flora.web.telegram.org/apiws

Getting Started 🚀

1. Clone or copy the repository contents.
2. Place dc.json at the project root (or use сfg.js embedded dataset).
3. Serve statically:
   • macOS/Linux: python3 -m http.server 8000
   • Then open http://localhost:8000/

How Latency Is Measured ⏱

• Primary: HTTPS GET to the DC host (mode: no-cors), 4 parallel attempts
  • Trimmed median: drop min/max, average the middle values
  • Prewarm DNS/TLS with a short fetch before the series
• Fallback: WebSocket handshake RTT if HTTPS fails

Country Search 🔎

• Loads from dc.json or сfg.js
• Accepts AT, +43, 43, partial numeric inputs
• Shows flag, country name, phone code, and DC assignment

Theme & Design 🎨

• Dark theme (default) and Light theme toggle
• Glass cards with blur, gradient borders, soft shadows
• Smooth animations: fade‑in, pulse, slide‑in results, hover glow
