My first thought is that it is something related to Jetpack. Maybe try deactivating Jetpack and see if those files are still being pulled from WP.com.
Also, I am assuming that you mean WordPress.com instead of ww.wp.xz.cn. Some people mix these up so just checking.
Thank you, Matthew. Yes, I did mean WP.com, which redirects to wordpress.com. WP.com is what it says in the site monitoring logs that my webspace provider has set up.
I have taken off Jetpack just after I wrote my post to see if it would make a difference. The first thing that I noticed, though, is that my site actually runs slower (!) without Jetpack. Could of course be coincidence.
I am also (still) getting two exotic error messages intermittently:
– Error 503 Backend fetch failed (varnish cache server)
– Error 504 Gateway Time-out. The server didn’t respond in time
What we are really trying to establish is whether the performance problems are site or server related.
My webspace provider thinks it’s the site, I think it is the server. Of course.
Which host provider are you using? Also which plugins do you have installed on your website? Which PHP version are you using? What theme(s) are you using?
Are you using any sort of CloudFlare service on your website? If so maybe try disabling that.
Host: Easyspace
CloudFare – nothing
Plugins – nothing exciting or dubious:
Add From Server
Akismet
All In One SEO Pack
Cookie Notice
Custom 404 Error Page
Disable Emojis
Email Subscribers
Fast Secure Contact Form
P3
Regenerate Thumbnails
Responsive Lightbox

PHP not sure but it will be an up-to-date version.
Theme: Matheson Pro
You could try disabling all your plugins to see if that fixes it.
That was one of the first things I tried. Unsuccessfully.
This is sounding more like a hosting issue then 😐
You could try switch to the Twenty Fifteen theme.
I started off with the Twenty Fifteen theme and it was not any different.
Then my best guess of the problem is your server.
What is your websites URL?
That’s my thought. My webspace provider is convinced there is something wrong with my site.
Website is http://www.wolfkettler.co.uk. Add /blog – don’t want it to be out in the wild too much because many elements do not yet work quite right, such as internal links.
The site is a rebuild on a new, clean database.
If you have disabled ALL your plugins, switched to a different theme, and disabled any CloudFlare sort of service then it can’t be something on your end.
I am curious if you website would still be slow if you moved it to localhost. I am convinced now that it must be something to do with the hosting and servers.
Hi Matthew
This will interest you: After we last spoke I ‘disconnected’ Jetpack and uninstalled it – and it seems that those three mystery images that I mentioned in my initial post did indeed come from Jetpack. At least they did not show up in the monitoring any longer. (Something else is still not quite right, though.)
Now here is the interesting bit: Today (!) I got an e-mail from Jetpack that my site was down and then some ten minutes later that my site was up again.
This is the ordinary Jetpack site monitoring but how can this be if Jetpack is disconnected and uninstalled?

Did you completely uninstalled Jetpack, or did you just disconnected it from your WordPress.com account?
I disconnected it, deactivated it and then uninstalled it from the plugins page. Do you think anything was left behind?
