A horizon server may be configured to reject historical requests when the history is known to be
further out of date than the configured threshold. In such cases, this error is returned. To
resolve this error (provided you are the horizon instance’s operator) please ensure that the
ingestion system is running correctly and importing new ledgers. This error returns a
HTTP 503 Error.
As with all errors Horizon returns,

||A short title describing the error.
||An HTTP status code that maps to the error.
||A more detailed description of the error.
