Internet Connectivity

Any IT professional will tell you that one of the most common issues is when users have problems with their internet connectivity. As we rely more and more on information pulled directly from the internet, connectivity issues only seem to be getting worse. We all know to check that the Ethernet cable is plugged in, that the computer is properly connected, and to do a release and renew of the IP address – but if none of those things work, there’s probably something wrong further up the network chain.
That’s because if all appears good in terms of physical connections and IP address configuration on a user’s computer, it probably means that there are some network performance management problems occurring on your network. The internet is a large entity, and while it is not impossible it’s still highly unlikely that it will go down. It probably has more to do with your bandwidth capacity and performance management on the system.
So, what do you do? Start by checking the performance of your network components. This would include the metrics of your switches and routers, as it’s possible that you may be experiencing bottleneck from these devices, perhaps based on capacity. Be sure to check your firewall as well, since it is a main interface to the internet.
Analyzing flow to see if you’re dealing with some potential bandwidth-hogging may not be a bad idea, especially since performance can be heavily impacted by high latency sites that stream video and music to users in their browser.
Once you’ve checked out the information about your components, and you need to keep looking, another potential issue could be a specific route that your network traffic is taking. This can be analyzed by using traceroute to detect troublesome hops along the way to IP addresses that should be universally accessible on the internet. Maybe it has to do with your provider to the internet, although this usually results in a slowdown as opposed to a complete loss of internet service. Still, should service completely go down on their end, it would be easy to detect by utilizing traceroute.
Remember, networking monitoring is about utilizing all the tools you have available to make sure that users can do their work. This often will require a multi-disciplinary approach in order to nail down the specific connectivity problem that you’re experiencing. Don’t give up, and eventually you’ll get to the root of your connectivity issues.
