That link actually includes the TRAPI servers, which do not return all data.  Anything not used by t at h is stripped out of the TRAPI databases.  Since my ROMA server is down while it rebuilds the database on a new disc array (SSDs!!), pretty much anything requested through that link will be returned by a TRAPI server.  I believe there will be separate links for the ROMA and TRAPI load balancers in the near future.

As far as I know, the ROMA servers return data as close as possible to the main API.  They should be no more than 3-5 minutes behind the main API.  Please correct me if I'm wrong (and I very well could be!).
