Internet failover is a secondary failover link that is there in the event of a failure in a primary internet connection. In the case of a disruption in internet connection where there would be a lack of internet resulting in internet downtime, the secondary failover link or secondary internet connection takes over for the primary internet connection to ensure internet uptime is not lost.
To simplify explanation further, in the event of failure in an internet connection, failover is simply the process of switching to a backup or duplicate internet connection until such time one is able to fix the problem that led to failure and hence restore the original connection to its primary working state.
In terms of the aforementioned problems relating to the necessity of internet failover’s implementation, the main internet link can fail causing internet outages due to various reasons, some notable examples being poorly done construction or traffic accidents, but also more extreme cases such as natural disasters or cyber security attacks. A failover link is itself another link separate from the main link that is setup to ensure internet is not lost. The following diagram provides ample illustration of this explanation.
Ensuring internet is not lost or disrupted and internet uptime is maintained is imperative in virtually all industries and organisations. An instance worth mentioning are commodity and funds trading companies which are reliant on constant internet, as even the most momentary of slips can cause potentially massive financial loss for investors. Some more instances in which internet is essential are in financial institutions such as banks and credit unions where internet downtime essentially translates to them being unable to operate, web/software development firms where lack of internet means less development, less collaboration with team members and possible missed deadlines, restaurants utilising point of sales software systems for ordering food and keeping track of inventory the health sector where hospitals have internet-critical applications core that can be termed as life enhancing systems. Essentially reliable internet connection is required in many industries and the organisations and businesses operating in them. This means having a backup becomes mission critical.
This brings us to the implementation of internet failover. How exactly is it accomplished? Well, as you would know, there are different types of internet connections. Most people think of wifi or broadband. However, businesses have different connection methods used to provide internet for their business and for many businesses, including those in industries whose complete reliance on internet is undeniable, a single primary connection is deemed sufficient, contrary to what lessons from internet failover teaches us.
To manage the risks associated with internet failover, establishing internet redundancy is paramount. Internet redundancy is simply reducing your reliance on any one source of internet connection, and as effectively as possible spreading that potential internet failure over various sources. An example of this is having fixed wireless as your primary internet service, and fibre optic as your secondary, which is wireless internet beamed directly to your building and incase of failure there is a fibre optic cable running to the building that takes over in the case of failure. The opposite can be the case. Today, innovative telecommunications companies are introducing applications such as 4G and bonding strategies to facilitate such redundancies.
Internet failover itself can be simply looked at as backup internet. In a time when internet connection is crucial, especially to a business or organization’s productivity, it is a method utilised to protect this connection, by creating redundancy. Relying on a singular method of internet connection is a risk.
