About IsItDownChecker

IsItDownChecker is a real-time website uptime monitoring and public outage detection platform. We check thousands of popular websites every 60 seconds from our servers, so you can instantly know whether a site is down for everyone or just you.

How It Works

Simply enter any website domain in our search bar, and we'll show you:

  • Real-time status — Is the site up or down right now?
  • Response time — How fast the site is responding
  • Uptime history — 24-hour, 7-day, and 30-day uptime percentages
  • Outage reports — Crowd-sourced reports from other users
  • Response time chart — Visual history of response times

Our Infrastructure

IsItDownChecker runs on dedicated servers with low-latency connections. We check websites using HTTPS requests and measure time-to-first-byte for accurate response time data. Our checks run continuously — every 60 seconds for the top 500 most popular sites.

Privacy

We don't collect personal data. IP addresses are hashed with a daily rotating salt before storage, and raw IPs are never written to any persistent store. We use cookie-less analytics to respect your privacy.
