Did some major work in a repo, and then suddenly find none of your routes working?
Maybe you blew away a .htaccess file that was being .gitignored ?

The default setup of laravel uses mod_rewrite. This wont work in our environment because we do not have mod_rewrite available.
My immediate workaround is to create a .htaccess that does this:
DirectoryIndex index.html index.php
and a splash page that client-redirects to index.php:
index.html:
<script>
window.location="index.php";
</script>
