Website Availability Guide
Check whether a website is down with independent external tests.
A page cannot reliably test arbitrary third-party websites directly from your browser because of cross-origin and network restrictions.
- Test from your device: Try opening the website in a new tab.
- Check another connection: Test from mobile data or another network to separate local issues.
- Use an independent checker: Compare results from a reputable uptime checker; do not assume one failed request proves an outage.
How to use this tool
Follow the steps above. Browser tests run locally when possible; other tasks provide practical troubleshooting guidance rather than claiming to scan your computer or network.
Important limitations
Results depend on your device, permissions, Windows version and network configuration. Back up important files before system changes and consult your device manufacturer for hardware repairs.
