It looks like most prod environments have something specific to one site in the oembed provider list for "file" and "node":
```
[node] => Array
        (
            [title] => Node
            [capture subpatterns] => 1
            [scheme] => #http\://projects\.iq\.harvard\.edu/stat110node/(.*)#i
            [callback] => oembedprovider_node_provider
            [provider] => 1
            [module] => oembedprovider
            [name] => node
            [path] => profiles/openscholar/modules/contrib/oembed/oembedprovider/plugins/providers
            [file] => node.inc
            [plugin module] => oembed
            [plugin type] => providers
            [cache] => 1
            [consumer] => 
            [weight] => 54
        )

    [file] => Array
        (
            [title] => File
            [capture subpatterns] => 1
            [scheme] => #http\://projects\.iq\.harvard\.edu/stat110file/(.*)#i
            [callback] => oembedprovider_file_provider
            [provider] => 1
            [module] => oembedprovider
            [name] => file
            [path] => profiles/openscholar/modules/contrib/oembed/oembedprovider/plugins/providers
            [file] => file.inc
            [plugin module] => oembed
            [plugin type] => providers
            [cache] => 1
            [consumer] => 
            [weight] => 54
        )
```
