Drop Lists for backorders

Registrars that wish to support the backorder market for domains, can utilise drop lists (or the equivalent data from an unavailable names report, or simply the EPP Check command response) to determine which domains are likely to become available for re-registration and take back orders in their sales process.

Drop lists are open and available to the public to enable the re-sale of names as they become available.

1. Drop lists are generated at the same time each day and published here. 
2. In the unlikely event of a technical issue with generation or publication of the list, then it will be published later in the day.
3. Two files exist per registry referenced as REGISTRY (e.g. REGISTRY will be replaced with ‘uk’ for .uk):
   1. REGISTRY.csv.gz which is the primary data file, it is a gzipped CSV with the list of all domains that are now pending delete.  We utilise gzip as that allows reading and parsing of the files without first decompressing them.
   2. REGISTRY.csv.gz.sha256 which provides a checksum of the data file.
4. Drop lists contain domains which have an RFC5731 domain state of pending delete which means they are either in RFC3915 redemption period or RFC3915 pending delete period.
5. Domains which are in RFC3915 redemption period may subsequently be renewed and removed from the next days drop list.
6. Domains in RFC3915 pending delete period cannot be restored and renewed and will drop at the specified time.
7. Domains which are deleted in their add grace period drop immediately and do not appear on a drop list.
