We got an email from the Serbian Registry of Internet Domain Names (RNIDS), the organisation that is responsible for the `.rs` top-level domain.

Looks like they are a big fan of Rust. 😊

@rust ccTLDs that are also programming langugage file extensions
.am Armenia, Automake
.as American Samoa, ActionScript
.cc Cocos (Keeling) Islands, C++
.gs South Georgia and the South Sandwich Islands, Google App Script
.ml Mali, ML
.mm Myanmar, Objective-C++
.pl Poland, Perl
.pm Saint Pierre and Miquelon, Perl module
.py Paraguay, Python
.rs Rust, Serbia
.sh Saint Helena, Ascension and Tristan da Cunha, Shell
plus many I've no doubt missed
@alex @rust As far as I can remember, paraguay makes it quite complicated to have a .py. First there has to be a second level like .com.py, and then I think you need to have a representant in paraguay. Also it’s about 250€/y.
So, not a lot of cool python projects in this space
