Two considerations here:
1) Copyright restrictions (especially US per sound recordings) may preclude
making the material publicly available.

2) While "bunker-like buildings" can be made resistant to all normal
events (i.e. excepting being a nuclear ground zero or the Sun going
supernova?) there is still the problem of fixed lifespans for the
medium used for storage. The building may well survive WWIII, but
when the mutant cockroaches reach intelligence to look for archives,
the disks that once were CD-R's may contain nothing!

Except that corporations, especially digitally-based corporations,
often have lifespans considerably shorter than we would desire for
data availability!
