New Post broken from Failed to load resource all.js from

Seems like an error on FB's end, but maybe there could be some improved exception handling in Ultimate FB plugin to prevent this from crashing post-new.php. Issue is that for some reason is now failing to load on admin pages. In the New Post page, this cascades and breaks other JS on the page and things like the auto post title > post URL and clicking the Add Media button simply don't work any more. This affects every site on our multisite installation. Has anyone else reported something similar / anyone else seeing this?

Any other option but to disable the UFB altogether for now? It's network activated and I know a lot of different sites in our network depend on different pieces. But currently none of our clients can really create new posts.

Many Thanks!
