A couple of things aren't quite right here: * They need to be in the build network (both IP-wise and DNS), currently appear to be in the office network. * moz2-darwinX-slave01 and 02 should be moz2-darwin10-slave01 and 02. We've already made the change on the machine, but the DNS needs to be updated, too. This is blocking the 10.6 ref platform, so I'm marking it critical.
222 IN PTR moz2-darwin10-slave02.build.mozilla.org. 223 IN PTR moz2-darwin10-slave01.build.mozilla.org.
