The OHR (Online Health Registry) was run by the same lady that runs K9 Data - Amy Raby.

If I remember correctly, a few years ago she ran into problems with the web host that was hosting K9 Data and the OHR. I think at the same time, she was working on opening K9 Data to Labs as well as Goldens and maintaining both. This was all while she was working full-time as a programmer.

I believe the decision was made to close down the OHR so that she could concentrate on expanding and improving K9 Data.
