The server is a computer system that provides a type of service in a computer network. The server also runs software that controls the network inside and gives network members access to the workstation.
If when accessing fails, it is usually more popular to call the server down. Server down means the failure of a system, where the server has a failure, which causes the server can not be accessed.
Cause Server Down
Many possible system failures, usually also occur on very long websites. Here are the possibilities that can happen.
1. Problematic DNS
DNS is a system that changes the website URL in the form of an IP Address. Make sure your DNS is installed on the hosting correctly or not, if your DNS has a problem then the server is not found, causing the website cannot be found at all.
2. A flood of visitors
Flooding of visitors or so-called soaring traffic, can cause down on the website being accessed. For website owners you only need to increase the capacity of web hosting. Or it could also by filtering a number of IPs that are suspected to be a cause of booming traffic.
3. Single Point Of Failure (SPOF)
SPOF is one of the weaknesses in the system. will occur failed, error and failed to fight, this will make the whole system stop functioning. How to eliminate SPOF by designing a good design and also planning hardware selection and monitoring that is disciplined in the running system.
4. Pirated Applications
Pirated applications can affect other hosting performance. Therefore you must be careful about installing applications that do not have clarity in hosting your website.
5. Natural Disasters
Natural disasters or natural disasters can not be predicted in advance, the right step you have to do is with recovery planning. With a disaster recovery plan for service providers, losses from service downtime can be minimized.
6. Power Outages
Power outages are also a factor in system failure, power failure can be a reason why services are inaccessible, or temporarily.
7. Hackers
Hackers are people who deliberately break into and take over the system, or even shut down the system. Hackers often attack systems that have security holes.
8. DDOS
DDOS is a person's effort to deliberately make the process of attacking the system simultaneously, this attack results in the system not running efficiently even to shut down the system.
