Server Status Checker

Network-level status, not just a web page check

Enter a domain or IP and this tool attempts a direct network connection to several common service ports - HTTP, HTTPS, FTP, SSH, SMTP, and MySQL - reporting which ones respond and how quickly. This is useful for diagnosing server issues beyond just "does the website load": a closed SSH port when you expect it open can point to a firewall problem, for example, separate from whether the web server itself is working.

Why checking multiple ports matters

A website can appear completely healthy on ports 80/443 while other services on the same server (FTP for file uploads, SMTP for outgoing mail, SSH for remote access) are silently unreachable - checking each port independently surfaces problems that a simple "is my website up" check would never reveal.

Why a closed port isn't automatically a problem

Many servers intentionally keep administrative ports like SSH, FTP, or MySQL closed to the public internet, or restricted to specific trusted IP addresses, as a deliberate security measure - seeing those report "closed" from this tool is often exactly the secure, expected configuration rather than a fault to fix.

What response time can tell you

The time an open port takes to respond gives a rough signal of network latency or server load between this checking service and the target - a port that's open but responds unusually slowly can point to network congestion or a server under heavy load, worth investigating further if it's consistently slow.

Preguntas frecuentes

Why would a port show closed even though the service is running?

A firewall between this tool and the server can block the connection attempt even when the underlying service is healthy - many servers intentionally restrict SSH, MySQL, and similar administrative ports to specific IP addresses for security.

Is an open port always a security risk?

Not inherently - web servers are meant to have ports 80/443 open to the public. Administrative services like SSH or a database port being openly reachable from anywhere is more often worth reviewing, since those are typically meant to be restricted.

Why check more than just the website's main port?

A site can look fully healthy on ports 80/443 while other services on the same server, like FTP or SMTP, are silently unreachable - checking each port independently surfaces problems a basic uptime check would miss.

What does a slow response time on an open port suggest?

It can point to network congestion between the checking service and the server, or the server itself being under heavy load - worth a closer look if the slowness is consistent rather than a one-off.

Can this check a server behind a VPN or private network?

No - it can only reach servers that are publicly accessible from the internet, the same way any outside visitor would need a public connection to reach them.
