Does old facebook page feed still work?

C开发者_如何学Pythonan we still access information using the old facebook page feed?

I have a client that still gets an rss feed from: http://www.facebook.com/feeds/page.php?format=atom10&id=...

Will this feed work for all public facebook webpages? and if so how long?

How come it isn't documented?

It's not document because the rss feeds are not meant to work like this. The right way to access "Public" posts of a page is:

https://graph.facebook.com/PAGE_ID/feed

You may also use FQL.
