SAM4_DFP pack page not available

The following SAM4_DFP Device Family Pack pages currently return "Page not found" (404):

www.keil.arm.com/.../
https://www.keil.arm.com/packs/sam4_dfp-keil/versions/

Is the SAM4_DFP pack still available? If so, what is the current link to the pack overview and version-history page?
Has the pack been deprecated or removed from the public catalogue?

Thanks.
