This table summarizes the days when data are missing, and summary files that are suspect due to missing data. Some data that are missing can be found in data from following days, because the file for each day ideally includes data from the previous 2 days as well as the current day. This was an intentional design decision to reduce the possibility of lost data due to technological problems.
