Degradation versus disruption definition

[stsnyder1]

Can anyone provide the definitions and the difference between degradation versus disruption on the service level?  Our entire traveler population cannot access Concur expense. To me it feels like a disruption but curious as to the definition of each?  Any guidance would be greatly appreciated!

I totally agree and the system is currently down as far as I am concerned.  There is no access and not even an ability to access for use.

@stsnyder1 here is what I was told:

Degradation would be service is degraded to some extent but not to the point of being completely unavailable (e.g., slow data transmission).

Disruption would be a service is temporarily unavailable, or that a system or equipment fails to function in a normal or satisfactory manner.

From what I've seen, seems like today was more a disruption than Degradation.
