Stanford Lecture: Dr. Don Knuth – Adventures with Knight's Tours [video]

They seem to have been embarrassed into putting the page back up for another few months. I think my first encounter with Stanford's website archival policies was when I found that they'd shot an old, once-much-hyped interview with Alvy Ray Smith into the void: https://news.ycombinator.com/item?id=28064844 . Anything on the Stanford website which purports to be education or history is a marketing op wearing a smiling mask, and when the marketing objectives have been met they'll delete everything with what seems to be a contemptuous glee, refusing to even use the Wayback Machine. Doesn't say much for that institution.
