Radix is looking for a back-end registry services provider, possibly ending its 10-year relationship with CentralNic (now Team Internet).
The company announced an invitation-only RFP covering all of its stable of TLDs: .online, .store, .tech, .website, .space, .press, .site, .host, .fun, .uno, and .pw.
.online alone has 2.6 million names in its zone right now; should it switch to a different back-end it would be the largest migration since 3.1 million .au domains changed hands in 2018.
Radix says its portfolio contains seven million domains altogether.
The company has put a September 16 deadline on interested parties returning their RFP forms. It expects to make its decision by the end of November.
