Uptime means periods during which a system is available and operational.

Uptime is the opposite of an outage, or downtime.


UK CBDC uptime targets may be 99.999%
"Current RTGS and CHAPS services have a target uptime of at least 99.95%, and that would constitute a minimum expectation for Bank of England-managed CBDC infrastructure.
However, we will explore whether a standard tailored to retail payments, where uptime targets are typically closer to 100%, would be appropriate and deliverable (in particular 99.999%).


Uptime targets are only one element of payment system resilience, and this target would be complemented by best practice risk management processes and controls.
There could also be minimum uptime requirements that PIPs and other service providers might need to meet."
