The term graceful degradation is often used as a technical term to describe a system that doesn't loose all its functionality at once, but is able to maintain some intermediary mode to remain partially operational.
What is the german term for that? On linguee.de one person used the term anmutige Verschlechterung, which sounds odd. The again, I could just call it grazile Degradation, but that sound even weirder. Dict.cc also suggests Fehlertoleranz, but that is a too strong generalisation of the concept.
Any ideas how to translate this nicely?
