Flared connections offer a high degree of long-term reliability and for this reason are often used in mission-critical and inaccessible locations.
This vulnerability will result in a lack of expertise in mission-critical areas if not addressed.
In general, real-time systems require predictable timing characteristics and robustness since they are used in mission-critical domains.
In addition, mainframes are still being used for some mission-critical applications, such as payroll, or for processing day-to-day account transactions in banks.
Professional payroll administration is mission-critical because of the magnitude of the remuneration by employers and the breadth of the legislative compliance requirements.
More than 2,500 pieces of emergency communication equipment (portable radios, fully charged batteries, chargers) and other mission-critical communication equipment were deployed to aid in disaster recovery efforts.
Marginal practices like these are strongly discouraged in large or mission-critical installations, because they can introduce extremely troublesome "intermittent" connections, as well as more-obvious outright bad connections.
This makes it very resilient and desirable for mission-critical applications.
