Yep, it's the Brazillian Olympiad in Informatics (OBI in Portuguese) website. All problems there are OBI problems. For those who cannot access the official website or don't know Portuguese, there's this. Just search "OBI" on the search bar and most recent problems should show up.

I think the reason, maybe, the hosting provider of those websites, Cloudflare, for example, proxies that blocked by your country, etc..

The gold medalists of INOI lead a group that helps people prepare for the INOI each year. They provide many OI-style, combinations, and graph problems. Shaazzz, their website, has useful blogs. and you can also use Shaazzz quide but they may need to be translated. Quera also has INOI final exam problems and OI-style problems, but they may require translation as well.

Hi, Vietnamese have this group. It has several OI-style contests and problem sets that you may find helpful. The statements, however, are most if not all in Vietnamese so you have to use some translator to read them.

This group is kind of an archive of old problems (we now have a new website for them), but they were practiced by generations of Vietnamese students so I believe there's still a lot of value in them. Some of the problems have editorial, you can PM me on Codeforces when you need them. Good luck!

Additionally since the group is unused, you can try visit our new website here. If you can access it, you can create an account on it and try some problems.

Unfortunately most of the problems are in Vietnamese, but there are still several English problems as well (for example ICPC national & provincial problems or VNOI Cup problems). Of course if you want to try out other problems as well you can use a translation service such as Google translate.
