As computing architectures become more disaggregated and virtualized, it is almost inevitable that outages caused by the use of many more network elements, platforms, suppliers, operating systems and applications will grow.
Multi-cloud computing, hybrid computing, edge computing and remote computing all mean that the availability of transport and access fabrics now is part of the availability performance.
Prolonged downtime is becoming more common in publicly-reported outages, Uptime Institute says. Also, outages are lasting longer.
The gap between the beginning of a major public outage and full recovery has stretched significantly over the last five years, with nearly 30 percent of these outages in 2021 lasted more than 24 hours, according to the Uptime Institute.
Human error also drives some downtime, in addition to network element, server, configuration or other software failures.
