What to do if an expired domain has locked you out of your Google blog
If you're seeing the message "You're about to be redirected, The blog that used to be here is now at..." and when you click on it, it's gone, your domain name has expired. Don't panic - a domain name is just a name, and your posts are are still there on Google, which hosts the files for you.
But you gotta get the domain working again to get to it, and if you hosted with Google, you need to go to https://domains.google.com, click on Manage my domains in the upper right hand corner of the page, and go renew it.
Yeah, it would be nice if Google had a message on the page that said something like, "Is this your domain? You can manage your domains here https://domains.google.com", but they don't. And anyway, not all domains are with Google. It could be GoDaddy, or about a million other companies. But if you distinctly remember registering with Google through Blogger, chances are very good that your domain is with Google Domains.
By the way, there is a difference between a domain name and a hosting site. A hosting site is where your files are, physically, and a domain is simply the name. Unfortunately many times files are hosted at one company and the domain is registered with another. For my clients, I strongly recommend that they keep the same company for hosting and domain.
I hope this helps. Let me know how it goes for you, we're all in this together.
