Service availability ≥ 99.9%
Formula for calculating service availability: **Normal service time in a service cycle/Total service time in a service cycle
Terms:
| Service cycle | It means a calendar month. If you have used the service for less than one month, the accumulative use time of the service in the month is taken as one service cycle. |
|---|---|
| Service downtime | If the error rate in a statistical period, in the unit of 5 minutes, exceeds 0.05%, the service is considered as unavailable in this statistical period. If Kingsoft Cloud CDN is unavailable in a time period of 10 minutes or longer, this time period is defined as service downtime. |
| Error rate calculation formula | (Errors that occur when the edge nodes of Kingsoft Cloud CDN are available in the statistical period + Requests that fail because the edge nodes of Kingsoft Cloud CDN are unavailable in the statistical period)/All requests in the statistical period. Errors that occur when the edge nodes of Kingsoft Cloud CDN are available in the statistical period: the number of 5xx, 403, or 499 errors that occurred due to system failure of Kingsoft Cloud CDN, configuration failure of Kingsoft Cloud CDN, or device breakdown in the statistical period. Requests that fail because the edge nodes of Kingsoft Cloud CDN are unavailable in the statistical period: the average requests in the statistical period in the last seven days on an unavailable node multiplied by the service downtime of the node in the statistical period. |
The errors that occur in the following cases are excluded from the statistics:

If the service availability does not reach the level stipulated in this SLA, Kingsoft Cloud will offer you compensation according to ten times of the service downtime.
Service downtime (in minutes) = Issue end time - Issue start time
Compensation = Average fee per minute in the month x Service downtime x 10
