I'd like to recommend Roy Fielding's definition.  It's more broad than
what's been suggested so far, but it seems bang on from my POV;

"Reliability, within the perspective of application architectures, can
be viewed as the degree to which an architecture is susceptible to
failure at the system level in the presence of partial failures within
components, connectors, or data. Styles can improve reliability by
avoiding single points of failure, enabling redundancy, allowing
monitoring, or reducing the scope of failure to a recoverable action."
