The security certificate is supposed to renew automatically, but my web host tells me that with the turnover of the new year, the independent company that issues the certificates can't keep up with the backlog. My web host tried to update it manually and still got a message that they are being issued in order.
Unfortunately, there is nothing to do but be patient and wait for them to work through the queue. Hopefully the problem will be corrected soon.
However, in the meantime, you can still enter the "unsecure" version of the website - it's perfectly safe. Just take out the "s" in the URL:
Go to http://rdanderson.com instead of https://rdanderson.com and the website should still function.
Feel free to spread the word.
