I think he's saying that he set up a web crawler to scrape python.org, and he was hoping that in the process it had made copies of those Wiki pages. He's apologizing that, as it turns out, the crawler did not make it to those pages after all.
Exactly. I thought my crawler had covered all of python.org, but it strayed off to stack overflow. Had not noticed due to the sheer amount of data it goes through. On one side, this sucks because I cannot help put the wiki back online. One the other, this led me to discover this bug.
I'd expect they'll find a way to restore the wiki content. The bigger concern is that someone downloaded their password file.
