Droplist (Drop Catch) Process

Has the drop catch process changed?

Yes, the new IRS droplist (drop catch) process is significantly different from the previous SRS one. Please refer to the technical forum slides 9th of September 2021, slides 15 - 21 for the details.

Also see the following from the Technical Changes Droplist section.

Plus the Interfaces Droplist API section.

Can registrars maintain connection to the TBR server (to-be-released (TBR) server) at any time?

TBR server connections behave exactly the same as EPP server connections, so connections can be made at any time; however, if any transactions are sent outside of a drop-catch session window, then the following error will be received: 8455 - Droplist session is not currently open.

What is the connection rate limit for the TBR server?

On a per connection basis there is a limit of 1 command per second. If a registrar submits another command less than 1 second since the previous command a time penalty limit of 10 seconds is applied. This means that the registrar now has to wait at least 10 seconds before submitting another command. If the registrar submits another command before the 10 second time penalty has expired another 10 second time penalty is appended to the limit. The registrar must then wait until any remaining time on the initial 10 second penalty has passed plus the additional 10 second penalty before submitting another command.

Please see the registrar portal help section ( Registry Services Concepts > Droplist > Rate Limits and Restrictions ) for full details how the rate limiting works.

There is also information on the TBR Rate Limits and Restrictions here

How long is each droplist session open for?

Each droplist session will be open for 1 hour starting at 2 am UTC.

What happens to a domain name not claimed from a droplist session?

Any domain name not claimed from a droplist session will be released for public registration immediately after the close of the session at 3 am UTC.

Where are the droplist servers located?

This is environment specific, please refer to Production Environment or Operational Testing Environment (OTE) specific documentation.
