Thanks to the Wayback Machine, the old NASA KSC “Next Gen” site is still available.
The “pre-2017” site contains *many* documents that were deleted in 2017 after policy changes meant not every document could remain publicly available.
Yet here it is! 100% archived. It’s true. The internet never forgets.

Adding a couple more years of content, the later KSC Next Gen site, since deleted by NASA, is available here too.
