The -S suffix is for a "subscription" branch that we make available to ISC support customers and others on request. It provides early access, in a supported and stable form, to features under development that are of particular interest to large-scale DNS operators. For example, the "fetchlimit" recursive client rate-limiting features for addressing recent DDoS attacks, which are in 9.10.3 and 9.9.8, were released first in the subscription branch while they were still experimental. Currently it also has negative trust anchor support and SERVFAIL caching, both slated for 9.11. Nothing in it is secret or closed-source; it's a just customized version of the 9.9 branch with certain 9.10 and 9.11 features backported into it, plus occasionally some experimental features that will be merged to 9.11 after we're satisfied with them. You can get all the same stuff by cloning the development branch in our git repository at source.isc.org.
