noun
failsoft
Computing term for a system designed to degrade gracefully rather than fail completely when a component fails.
このサーバーはフェールソフト設計なので、一部が故障してもサービスは継続される。
This server has a failsoft design, so service continues even if part of it fails.
フェールセーフ (fail-safe) focuses on safety by shutting down or moving to a safe state, while フェールソフト (failsoft) emphasizes continued operation with reduced functionality.
Borrowed from English 'failsoft', a compound of 'fail' and 'soft'.
