VagrantBox.es is a pretty awesome project for anyone looking for some simple commits.
Basically, it's an index of the Vagrant machines which are available for use, that isn't tied to the Hashicorp atlas (it was there first :) )
We've got some open #Hacktoberfest issues at the Github project page but the key one for me is #395 which is where a very kind individual identified all the boxes which weren't replying with a useful HTTP response (either 404, 401, or 429). Unfortunately, it was so big, we can't easily read back and work out who submitted these boxes, to check why they're offline.
I'd like someone to find a few of these, and submit a PR containing just that box (or associated boxes, if they're at the same URL) so we can remove them specifically from the index (and if the owner has moved them somewhere, perhaps you can amend your PR to point to the new location?)
And I'm more than happy to work with someone to get these changes made. Contact me @JonTheNiceGuy on Twitter or firstname.lastname@example.org by email
