On January 23, 2025, the CSCS officially shut down the Piz Daint supercomputer.
From Wikipedia:
It was ranked 8th on the TOP500 ranking of supercomputers until the end of 2015, higher than any other supercomputer in Europe. At the end of 2016, the computing performance of Piz Daint was tripled to reach 25 petaflops; it thus became the third most powerful supercomputer in the world. As of November 2021, Piz Daint is ranked 20th on the TOP500.
