FWIW, I have seen sites suddenly leave for whatever reason and years of info disappeared with it. No explanation, no warning, nothing. Yesterday the site's there/normal; today it's gone as if it never existed - click on your link and you just get a "site does not exist" or similarly worded message from the search engine.
So, I suggest that if there is interest in ensuring that the OB tech data be available if they shut down, some steps be taken to coordinate with them/copy the info. Obviously, anyone can download/copy the tech articles from the OB site but posting publicly without their permission might be a copyright issue. I don't know if that's the case on the Web - maybe everything is considered public info once published and copyright/ownership does not apply. But worth being sure about.
If nothing else, it's the right thing to do - talk to Fred/Ella first and then proceed.
