I wanted to just post the video, which has a lot more information (though not the kind of info you’re looking for), but I didn’t know if an LTT video was an “official” enough source for this community.
I suppose this was probably the first time that all of the digits of pi up to 300 trillion were calculated, even if the 300 trillionth specifically was already known.
They did use Y-cruncher.
Edit: Some other fun tidbits: most of that 2.2 petabytes of storage wasn’t actually used to store the 300 trillion digits itself - that number of digits fits in like 170 terabytes (which LTT is thinking of making available as a download, lol) - it’s actually used as pseudo-ram during the actual calculation.
