On Wednesday, 14 August 2013, ARIN finalized the adoption of an extended statistics file format in accordance with Number Resource Organization (NRO) statistics file standardization, and has deprecated the previous, standard statistics files. The new format has several advantages which may be reviewed at https://www.arin.net/reference/research/statistics/nro_extended_stats_format.pdf. This change was first announced to the community in February 2013 (https://www.arin.net/announcements/2013/20130219.html). In July 2013, ARIN announced that the previous statistics format would be deprecated in August (https://www.arin.net/announcements/2013/20130710_stats.html). Upon deprecation on 14 August, ARIN announced the discontinued availability of standard statistics files (https://www.arin.net/announcements/2013/20130814.html). The announcements referenced above were posted to the ARIN website and to the arin-announce@arin.net mailing list.
