Nine months ago E869120 wrote a blog informing us of the decision to host IOI 2025 at La Paz, a city with an altitude of 4100 meters at the airport and 3600 meters in the city, an elevation with a guarantee of massively decreased cognitive performance and even a chance of dying. https://codeforces.net/blog/entry/128667

Today IOI 2025 was moved to Sucre, a city with an altitude of 2750 meters, substantially reducing the problem.

I believe this would not have been possible without E869120 bringing it to public attention.

THREE CHEERS FOR E869120!
