The current version of WordPress is 4.9.2, so I have no idea why the other emails are referencing 4.7.9. Have you checked the actual databases on these three sites using Phpmyadmin (or whatever tool your host provides).
Try
Error Related to Missing or Damaged Core Files
Try downloading WordPress again, access your server via SFTP or FTP, or a file manager in your hosting account’s control panel, and delete then replace your copies of everything except the wp-config.php file and the /wp-content/ directory with fresh copies from the download. This will effectively replace all of your core files without damaging your content and settings.
Some uploaders tend to be unreliable when overwriting files, so don’t forget to delete the original files before replacing them.

Thanks Guys
One of the sites has come back on its own but not the other two.
Looking on the server now it does say those two databases not available so not sure whats happened. The trouble is I don’t actually control that server so I will have to try and contact them to find out why its gone.
Thanks again, Chris
Had the same problem: email re. update (in my case to WP 4.2.19), then site offline.
However, in the time it’s taken me to sign up to write this post, the site is back online again. Hopefully your other ones will return shortly too.

I think this issue comes from your hosting. I hope the rest of site coming soon.
Thanks

Hi!
Don’t worry everybody, all sites are back online now after this issue…!
Chris.
So not a hosting problem at all then…
Many, Many thanks for your replies.
Now they are all back thank goodness. Very relieved.
I must make sure that backups are properly done, what would you recommend?
Thanks again
For backups, Updraft plus plugin is vey simple and efficient. Or another… (Thank you, Rajan)
Chris.

If you want a premium service, you should look at https://vaultpress.com/ (it’s an Automattic service, so you know it’s always going to work with WordPress)
If you want a free solution, have a look at the backup plugins at wordpress.org.
Finally, see if your host offer anything as part of your hosting package.
