        An entity fetching geofeed data using these mechanisms MUST NOT
        do frequent real-time look-ups to prevent load on RPSL and
        geofeed servers.  <xref target="RFC8805"/> Section 3.4 suggests
        use of the <xref target="RFC7234"/> HTTP Expires Cacheing Header
        to signal when geofeed data should be refetched.  As the data
        change very infrequently, in the absense of such an HTTP Header
        signal, collectors MUST NOT fetch more frequently than weekly.
        It would be wise not to fetch at magic times such as midnight
        UCT, the first of the month, etc., because too many others are
        likely to do the same.
