I just talked to someone at WordPress support, and they said the problem only seems to be affecting custom sites. That means, if you have .wordpress in your site’s address, you shouldn’t be affected. If you pay for your site and you don’t have a .wordpress.com site, and your pingbacks don’t work, please let support know.
Proof that they’re doing something: I got a pingback tonight. Problem was, it was from Margret’s post here:
https://writingandreadingashobbies.wordpress.com/2016/04/13/fortune-cookie/
but the link pinged back to here:
https://lindaghill.com/2013/04/21/how-comments-can-hurt/ – a post of mine from three years ago.
Weird. Hopefully things will be back to normal soon.
Have a good night all!

Hmmm, mine has a custom domain without the wp.com suffix, but I’m still having problems.
Plus, still cannot comment on any Blogger sites.

Thanks Linda. I have a custom URL, but my site is on WP, and pingbacks are not working 😦

I use self-hosted WordPress with Jetpack. Pingbacks never seem to work.

How strange!
I know I tried to pingback to one site and when I tested the link it went to a different post of theirs… But then I tried it again and it worked!

Weird. I haven’t heard about this, but then, I haven’t been noticing much lately. Involved in getting life straightened out at the moment.

What about themes not showing up? Has anyone had a problem with that? I have my own site (without wordpress in the name) and when I post it does show up in the wordpress feed but it does not show my theme or anything which is really discouraging.
