For an application with a 99.99% availability SLA, which downtime would indicate success during testing?

An application with a 99.99% availability Service Level Agreement (SLA) indicates that it is expected to be operational 99.99% of the time over a given period. To put this into context, for a whole year, this translates to a permissible downtime of about 52.56 minutes. When assessing the implications of various downtime periods, the key is to understand how these times align with the expected availability percentage.

In a scenario where the application experiences only 1 minute of downtime within a specified timeframe, it clearly demonstrates that the application is well within the acceptable limits established by the SLA. In fact, this amount of downtime is significantly lower than the maximum allowed downtime for a 99.99% availability level, showcasing robust performance and reliability during testing.

The option expressing 4 minutes of downtime also suggests success but approaches the upper limit of what's permissible under the SLA, meaning while it still meets the criteria, it does not reflect as strong a performance as the 1 minute would. The further options—10 minutes and 30 minutes—exceed what would be acceptable under the 99.99% availability expectation, indicating that they would not be viewed as successful during testing given the SLA's stringent requirements.

Therefore, experiencing just
