Frequently Asked Questions
Common questions about website downtime and monitoring.
Why is a website down for me but not others?
This can happen due to DNS propagation delays, regional server outages, ISP-level blocking, or CDN issues. Your local DNS cache may also be stale. Try clearing your DNS cache or using a different DNS server like 8.8.8.8.
What causes a website to go down?
Common causes include server overload from high traffic, software bugs or crashes, expired domain registration, DNS misconfiguration, DDoS attacks, hosting provider outages, expired SSL certificates, and scheduled maintenance.
How accurate is this tool?
This tool checks from our server's location, so it reflects whether the site is reachable from our data center. If the site is down only in certain regions (due to CDN or geo-blocking), results may differ from your local experience.
What should I do if my website is down?
First, check if the issue is DNS-related or server-related using this tool. If DNS fails, verify your domain registration and nameserver settings. If the server returns an error, check your hosting provider's status page, review server logs, and contact your hosting support.
