Where did everybody go?

OK, everyone who has ever visited my blog is gone.  The stats section has been wiped out, along with scores of comments, followers, you name it.  It’s as if someone or something came through.  I hadn’t noticed before, but it looks to have happened a day or so ago.  Anyone know what happened and why?  All the posts appear to be there, though I haven’t checked to see if images, videos and links work.  But either half or all of many other things are gone.  Wonder if it’s a glitch like the one that hit a year or so ago.  Any ideas, please feel free to let me know.
