# CKError.Code.zoneBusy

An error that occurs when the server is too busy to handle the record zone operation.

## Declaration

```swift
case zoneBusy
```

## Discussion

Discussion Try the operation again in a few seconds. If you encounter this error again, increase the delay time exponentially for each subsequent retry to minimize server contention for the zone. Check for a CKErrorRetryAfterKey key in the userInfo dictionary of any CloudKit error that you receive. Use the value of this key as the number of seconds to wait before retrying the operation.
