Another cause of service outages is network connectivity. A loss of connectivity resulting in downtime can lead to a number of negative business impacting events.
What causes a loss of connectivity?
- Equipment failure
- Software crash
- Human error
- Denial of service (DoS) attacks
- Fiber cuts
Companies that manage network connectivity in-house to support mission critical applications are more susceptible to experiencing downtime due to loss of connectivity, as it is cost prohibitive to design the same level of redundancy that a commercial data center provider would implement. Typically, the capital cost and monthly operating costs of establishing a fully redundant and resilient network in addition to supporting such a network is prohibitive. As such, these companies will make use of one Internet carrier, creating a single point of failure.
Furthermore, companies that manage network connectivity in-house:
- Will not have access to the number of different carriers that a data center provider does
- May not be multi-homed
- May not utilize BGP (Border Gateway Protocol)
- Are probably only able to use a single network provider; if using more than one, they’re relegated to one physical fiber entrance.
All data center providers should offer a redundant network setup—this is common to the industry, and a standard benefit to utilizing a data center partner.
