The wipe has not happened yet. Unless you were in Molecular Blue version, of course. If you were not, then ask yourself these questions:
1) Did you have another account? If so, try logging into that one
2) By any chance, did anyone else have access to your account? If so, they may have deleted the character.
3) The planeshift team might have thought that "Boneyard" is an invalid name. Have you read th echaracter naming policy? Once they block a name, you may not be able to use it again.
Hope I helped.
