Can't find chzoom-1 of VirtualBox

[cweiming]

Hi there,

I followed the method in Running in virtual environment, but got error messages as below:

$ vagrant up
Bringing machine 'default' up with 'virtualbox' provider...
==> default: Box 'chzoom-1' could not be found. Attempting to find and install...
    default: Box Provider: virtualbox
    default: Box Version: >= 0
==> default: Box file was not detected as metadata. Adding it directly...
==> default: Adding box 'chzoom-1' (v0) for provider: virtualbox
    default: Downloading: http://beta.chromozoom.org/files/chzoom-1.box
    default: Download redirected to host: github.com
The box failed to unpackage properly. Please verify that the box
file you're trying to add is not corrupted and that enough disk space
is available and then try again.
The output from attempting to unpackage (if any):

bsdtar: Error opening archive: Unrecognized archive format

It seems to me that the domain of "www.chromozoom.org" has been crashed. It's probably a cause that the box 'chzoom-1' could not be found.

Any help would be appreciated.

Thanks!
