.fr Rush -unfortunately ?- does not refer to a partnership between AFNIC, the .fr registry and the Canadian band Rush.
It is a new service dedicated to Snapping launched in December 2016 by AFNIC. The term snapping, more commonly referred to as snapback consists in automatic queries aimed at re-registering a previously registered domain name as soon as it is available again.
So far, regarding TLDs managed by AFNIC (notably the .fr) the registrars offering this service to their clients had to use custom tools allowing them to automatically,and repeatedly send queries to AFNIC production servers in order to automatically register newly-available domain names.
In order to lighten the load on its production servers, AFNIC has taken two measures, namely:
Creation of a penalty / temporary ban from production servers in case of abuse by registrars with their standard access (snapping activities are still allowed but subject to limitations);
Implementation of a paid service using a server dedicated to snapping activities, more tolerant towards automatic queries in terms of frequency and patterns.
Access to this .fr Rush server is leased to registrars for a limited (and renewable) period of time. This new service allows the multiplication of automatic queries aiming to register a soon-to-expire domain name and can be used in combination with the regular solutions used so far.
It is important to keep the existence of this service in mind, particularly in the case of a domain name supposedly sought after by more than one person or entity (eg. short and/or strategic domain names).
The IP TWINS team remains available to advise and assist you in the recovery of domain names, under .fr, other ccTLDs and generic TLDs, notably through snapping services.
