Network Monitoring

If your company's website is any bigger than one page, essentially it is its own network. Monitoring your network is crucial in order to make a good impression on your visitors. Any time your site goes down, your company can lose thousands, if not millions, of dollars.

What is Network Monitoring?

Most companies own or use the following: DNS servers, FTP servers, firewalls, and POP or SMTP servers. Website monitoring services that monitor networks can keep track of any or all of the above. The ideal service will be able to track your site from different points around the world, ensuring that you site is accessible globally.

DNS servers translate your URL into a numerical IP address that computers can read. If your DNS servers are down, your visitors will not be able to access your site. A monitoring service will alert you if this happens. FTP servers, which allow you to exchange files with remote users, can also hinder your website's performance if they are not functioning properly.

Your company probably uses a firewall to protect your internal network from being harmed by viruses, worms, spyware, and cracking into by outsiders. It's your first line of defense and if it goes down, your whole network can become inaccessible. If you host your own mail or web servers and your firewall goes down, users can't access your network and will get error messages. Again, a network monitoring service will be able to detect these problems and quickly get them resolved.

If your company uses email, (and what company doesn't these days?), chances are you are using SMTP or POP3. When these don't function, emails to your company bounce back to the senders and you don't receive them. That can leave a horrible impression with your customers. Once again, a website monitoring service can also monitor your email servers, whether you own them, lease them, or have them hosted remotely.
