🌏 Introducing Port monitoring [new feature]

Is your email SMTP service working correctly?

Maybe you've been having intermittent issues with your emails lately, well, this could be cause by improper port configuration on your website's email server.

Today, we're pleased to announce that you can keep an eye on these ports along with many others with our brand new Port monitoring monitoring type.

You can start using this today, but first, a little more on this new feature...

💪 Why monitor ports?

There are many different ports available on your server, typically, the most common two that you might be familiar with are:

  1. Port 80 (HTTP)
  2. Port 443 (HTTPS)

These ports are the ports that your website's webserver uses to serve webpages to your potential customers, usually, these ports, when they break will cause some kind of error screen for you and your customers.


Other ports, such as port 22 (SSH) or even your email's SMTP port 25 might be currently broken and you could be unaware of this.

When did you last make a change to these?

Have you recently checked their availability?

Automating the checking using port monitoring is vital to ensuring that they're working, all of the time, both day, and night.

👀 What are the common ports?

There are many different ports, but here's just a few of the most common ones:

  1. 80 - HTTP
  2. 443 - HTTPS
  3. 25 - SMTP
  4. 21 - FTP
  5. 22 - SSH
  6. 23 - DNS
  7. 143 - IMAP
