There are several link-related bugs reported but I couldn't find this one. Here is a blog comment that includes a link to the discussion:
But if I click on the link, it leads to a completely different page: Thread-Dumps and Heap-Dumps for SAP CPS - SAP Blogs
It seems that even though the link was for a discussion, just because it appears in a comment to a blog, for some reason it got redirected to blogs.sap.com, which is incorrect.
OK, Jelena, I received confirmation that this is indeed one of the things about redirects in blogs that they've been working on. Check your example after the re-migration on Tuesday (Oct 4) and let me know if it solved the issue.
