Subject: Monitoring Internet Service Using eCyberForce MacroProbe v1.4
We connect to the Internet via mobile subscriptions, home networks, or work-based services. But what happens when the Internet service goes down? Without connectivity, we’re unable to access online services. To better understand how the Internet service works and the potential issues that can arise, let’s take a closer look at its components.
Understanding Internet Service Components
The Internet is a multi-protocol service, relying on both DNS (Domain Name System) and HTTP (Hypertext Transfer Protocol) to function effectively. When you enter a URL like http://google.com in your browser, your computer sends a DNS query to resolve the domain name (e.g., www.google.com) into an actual IP address associated with the nearest Google server.
Typically, your computer is configured with default and secondary DNS servers. If your computer cannot resolve the domain to an IP address, the DNS server will fail to respond, and you won’t be able to access the site.
In cases where the DNS server is down—or both the primary and backup DNS servers are unavailable—your computer cannot resolve the domain, and the Internet service will appear to be down due to a domain failure (such as a DNS server failure or a server refusal error).
What Happens If the DNS Works, but the HTTP Service Fails?
If the DNS servers are functioning properly and can resolve http://google.com to a valid IP address, but the local Google server serving your area is down, this is an example of HTTP transport failure. Even though DNS resolves the domain, the HTTP service cannot provide the requested content, resulting in an error such as an HTTP 500 (Internal Server Error). In this case, Internet service is still considered down due to the failure of the HTTP service.
Monitoring Internet Service: DNS and HTTP Dependencies
When monitoring Internet service for outgoing traffic, it’s crucial to understand the interdependencies between DNS and HTTP. The service relies on both protocols working together for end-to-end service delivery. This means that monitoring should focus on the relationship between DNS and HTTP, rather than just one or the other.
