Those links are to "Open Access" books and have always, I believe, been free (as in beer).
The content identified by the original post were not open access; they were paid access (typically quite expensive) and published in 2004 or before.
I hope the zero cost downloads was not a glitch but a policy, and that Springer will make those older texts freely available again.
