Europe's first geostationary sounder satellite is launched

I think this is the first time I have seen the .int tld used.

It isn't super popular, no. I think the requirements are pretty strict if I remember correctly (edit: https://www.iana.org/domains/int/policy).

I think esa.int is probably one of the more popular .int domains on HN: https://news.ycombinator.com/from?site=esa.int

Other notable .int domains:

• World Health Organization - https://who.int

• NATO - https://nato.int

• Council of Europe - https://coe.int

• Mercosur - https://mercosur.int

• African Union - https://au.int

• EFTA - https://efta.int
