Depends on the changes I’d say. If it’s a change marked as `[BREAKING]` then definitely it’s safest to provision a new server. If for example we changed the template of an Nginx config file, it’s likely fine to re-provision an existing server.

We don’t really provide that information beyond `[BREAKING]` so it’s a bit of a judgement call. All that being said, provisioning a new server is a great habit anyway in my opinion. It’s what we do for the [roots.io](http://roots.io) site. It can be heavy-handed and take more time, but it’s safest in the long run.
