I apologize to all for the complete disappearance of the website for over 24 hours. It was caused by my managed server being "managed" by a third party, to include an important "security" update. Apparently the managers forgot to restore the backup, or they forgot to plug the server back in.
Whatever the cause, the website is almost back to normal, except that the domain opefs.com does not yet connect, which is just a small challenge. Most business is transacted via ehabich.info.
