Access to the images which were not working earlier has been restored. Happy building!

Investigating
We've received some reports of builds not starting on our OS X infrastructure. It seems to happen to specific build images only. So far the `xcode7.1` and `xcode8` images have been showing the behaviour. We are looking into it and will provide an update as soon as we know more. Thank you for your patience.
