A horizon server may be configured to only keep a portion of the stellar network’s history stored within its database. This error will be returned when a client requests a piece of information (such as a page of transactions or a single operation) that the server can positively identify as falling outside the range of recorded history.
As with all errors Horizon returns,

||The identifier for the error. This is a URL that can be visited in the browser.
||A short title describing the error.
||An HTTP status code that maps to the error.
||A more detailed description of the error.
||A token that uniquely identifies this request. Allows server administrators to correlate a client report with server log files
