Yes, as long as it caches the correct DNS answers. For the occasion that
the answer from the upstream DNS is incorrect, it will get cached as
well. This could result in a longer time for problems, I think.

I do not know what exactly is wrong with the DNS responses
build.gluster.org gets, or where the faults get introduced. Until we
understand what is going on, I'd be careful with caching those
responses.
