Did Moz recently change how it calculates keyword difficulty?

Did the keyword tool recently change? What is Grepwords? Why do all my long-tail phrases show as "not available?" Just wondering...

Hey Allison!

We did make an unexpected change due to losing access to Bing's API for their search volume. We found that Grepwords' API has access and for an emergency solution we worked out an arrangement to partner with them to restore access to Google's Search Volume, which we lost direct access to a long time ago. We are seeing some long-trail phrases return no results but are not seeing any issues, Google may not have data for those keywords.

Hope this helps!

I see over 50% "not available" for keyword volumes (when working with swedish keywords). These are not long-tail keywords and Keyword Planner in Adwords show these as having search volume.

How can this be?
