The data set is refreshed on a weekly basis on Fridays at 2:45 AM. The website will reflect the last time the data set was updated and the total count of rows. The grid on the "Data" tab will display the up to date data. However, in certain situations there is a delay in the refresh of the downloadable data file. Sometimes the downloadable file does not reflect the updates to the data in the portal. After a delay (duration has been variable; up to 30 minutes), the file will be updated on the server and then downloads will include the updated data.
