The server the site is hosted on is having filesystem problems, and someone is looking at right now.  I’ve got a good full backup (I know it restores OK) from Monday, and managed to save some of the newer reviews first thing this morning, but I’m not hopeful about some of the very recent reviews and comments. I think I’m going to spending the rest of the day rebuilding things once whatever hardware failed is replaced.

Hopefully all will be back to normal later (probably much later) today.

Apologies for any inconvenience caused.
