Instant availability check from our global node
Often, a website might be inaccessible due to your local ISP issues, DNS cache, or firewall settings. Our tool checks the website from an external, neutral server to confirm if the downtime is global or local to you.
Understanding the error code is key. 500 means the server crashed. 502/503 often means the server is overloaded or under maintenance. 403 means access is forbidden.
