Network Reliability
True that the internet from the local to the global network has improved greatly in the way it works as it becomes part or forms the Internet. There are still many issues like reliability that continue to be tested each and everyday behind our backs as we click away on our keyboards and mice. Many network monitoring systems like the Global Emergency response centers in Singapore, who keep watch over the internet for new threats such as viruses and worms that can cause global chaos (well to the internet that is). These people employ the best in their fields, from programmers, system analysts, network specialists and technical advisers as they attempt to beat threats before they set the internet on fire so to speak. Previous attacks have left us with no internet service for days as worms flood web mail servers with excessive junk email which eventually slow and even shut down due to lacking disk space and bandwidth. These attacks have had new links formed in hopes of taking over failed links in the net so if they were to happen the internet would re-route itself to new connections as if there was nothing wrong. The problem is then localized and then finally neutralized which can leave damages in the millions of dollars in lost revenue for web based businesses.
