No, that’s not what’s happened. And yes, it was an error on “your” end, though it seems to be resolved now.
Only the first link has been removed and normally when I click on a removed link I get sent to the 404 error on that site (which is what is happening now). Not an unhelpful page on your intermediary’s site.
The second link (and others on the thread - I didn’t bother to put in every example) is not to a removed link.
Whatever the issue was goskimmeresources seems to have resolved it for the moment and the links I gave you are forwarding to the sites they are supposed to. But they weren’t taking me there at the time, they were taking me to an error page on goskimresources.com. Next time I’ll screenshot it.
