Virtually any company that relies on a public (or private) internet connection runs the risk of developing manual DNS outages from time to time. However, those who do not have an in-house IT department may suffer more greatly from the faults in manual failover, which includes extended downtimes. The following industries are examples of how outages can disrupt important operations:
Healthcare Institutions: Hospitals and other healthcare practices rely on the internet to transmit orders from doctors to nurses, upload patient information, and handle video calls between multiple departments. A DNS outage could completely disrupt the processes within a hospital, causing all patient care to grind to a halt. This can cause extreme negative impact on patient health, even leading to death in extreme cases.
Educational Institutions: Today, numerous schools and universities rely on the internet to administer tests, communicate with teachers and students, and upload educational materials. Without reliable DNS connections, the quality of student education suffers.
Airlines: Airlines run thousands of flights each day, needing a tremendous amount of data to do so. Therefore, an outage that causes inaccessible data can delay flights and cost the airline a significant amount. For example, Delta Airlines had an outage occur at one of their data centers for only 5 hours, yet due to thousands of grounded flights, the outage cost the company 150 million dollars.
Due to the immense impact an outage can have on a business’s operations, it is important to understand how the failover process can be improved.
