It depends.

In domains where software is expected to run for years, if not decades, it's common to archive the entire toolset, along with libraries and SDK's in case you need to fix a bug/add a feature 10 years later. Obviously, in this case you can't have dependencies sitting somewhere on a server you don't control.

There are also situations where this is forced by regulation: you need to recreate build xxx.yyy.zzz 7 years after release because a customer reported a serious bug and it needs to be reported to the relevant regulatory agency and investigated.
