How does this affect you?
When you try to update your collection on our site, you'll likely receive a "Character unavailable" error. Typically this indicates a problem with your Armory profile. If you were to try to pull your profile up in the Armory, chances are, it won't load.
The error must be fixed on Blizzard's end before you will be able to successfully import your pet collection and correctly reflect your in-game progress.
When will it be fixed?
Blizzard is aware of the problem and currently looking for a solution. For more information, check the following thread on the official WoW forums:
Discussion of this Issue in WoW General Forum
There's no ETA on a fix, but they are working it. So hopefully SOON™
We apologize for the inconvenience. Unfortunately, this issue is out of our control.
Why not bring back the WCP Addon?
With the increase in realm merges and Armory errors following those merges, more and more of our users have been running into issues when trying to (re)import their collections.
It's been suggested that we restore the WarcraftPets Express Addon that we used to offer to enable importing via a unique code assigned in-game by the addon.
We may consider this option. But for now, our hope is that Blizzard will continue to repair and maintain the Armory, as it offers our site (and many others) data and functionality that would be difficult to replicate via an addon alone. More info
