If it's been down for a few weeks it's too early (as you say) but a good idea to mention it now. Your query points to about 600 answers, this is a lot, so the hope, if it's once judged time to make a change, to do it in an automatized way (which can be done only by moderators, I guess). Maybe some preparatory work should be done prior to detect what is the ...

I guess I usually act as follows: a) If I know how to fix the link (typically, link points to an identifiable paper), I either edit accordingly, or add the link as a comment (I might even provide 2 links, e.g., link to journal, often behind paywall, ideally using DOI, along with arXiv link); also I might add the journal reference when it wasn't initially. b)...

To get a link to a comment, simply click on the timestamp next to it. (If it is your comment, be careful not to click on "Delete" by mistake.) For example, this is a link to the first comment posted below this answer. It is possible to get link to some specific comment also from other places where you might see that comment. (Such as user's ...

I've managed to find copies of 6 links in 5 posts which were archived in the Wayback Machine, and they have been updated (thanks for reviewing!)

The question must not be deleted, and linking to answers doesn't work. Links ...

Since it seems that this is not common knowledge, I'll add an explanation of one way that gmane can still be accessed. I know there are some people knocking about here who were accessing email in Emacs long before Sir Tim had even thought of the WorldWideWeb, but I wasn't, and in fact I didn't have any idea how to do it until shortly before posting the ...

This answer is intended for testing. Please include the source code used in the comments into the answer — so that we can check when the link works and when it doesn't. 1 $\DeclareMathOperator{\Hom}{Hom}$ [link](http://mathoverflow.net) $\Hom (U\times V,W)$ and [another link](http://mathoverflow.net). 2 $\DeclareMathOperator{\Hom}{Hom}$ [link](http://...

I have noticed that this was discussed in the comments to this question: Privacy of software-generated links to questions and answers. (Which was bumped not too long ago. The linked discussion mostly focuses around the fact that from the "share" button you get the link which can also identify the user copying the link and the possibilities how to ...
