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.
