I was hoping to find more info on the "250% nominal load" mentioned in the title. However, I didn't see anything about load on the linked page, just a generic looking donation page.

I'm a bit biased, because I focus on CPU efficiency for a major CDN, but I'd be super curious what exactly is at 250%? Network bandwidth? CPU? IOPS? Are there big hammers that they can use to get things back under control without adding servers, like reducing bitrate, or turning off "fancy" features?
