The link not working...

Yes... I think it's for internal use only (from within the Googleplex).

I like the .borg. part :o)

And did Google always showed so much "details" on their internal structure, like that link, the Google Search stacktrace and more?

Possibly a move to thwart Yahoo Finance ?

Yahoo just recently updated their finance site so this could be Google's answers to this.
