I have noticed that the data.okfn.org home page redirects to frictionlessdata.io. That website, in turn, has no easy to find link to search for the data packages themselves, instead only linking to the data package specifications, tools and documentation.
The other day I wanted to find the comprehensive country codes but had a hard time locating it. I had to resort to advanced queries in a search engine and fortunately that page had been indexed before.
I think this should be fixed. Maybe frictionlessdata.io should have a "search for data packages" button somewhere on it, directing visitors to http://data.okfn.org/data .
