Nature does it all the time. Here's one I fixed just this morning when I noticed it by accident: http://www.nature.com/mp/journal/vaop/ncurrent/full/mp201522... (Note, by the way, how very helpfully Nature redirects it to the homepage without an error. That's what the reader wants, right? To go to the homepage and for Nature to deliberately conceal the error from the website maintainer? This is definitely what every 'archival quality' journal should do, IMO, just to show off their top-notch quality and helpful ways and why we pay them so much taxpayer money.) Oh, SpringerLink broke a whole bunch which I am still fixing, here's two from yesterday: http://www.springerlink.com/content/5mmg0gmtg69g6978/ http://www.springerlink.com/content/p26143p057591031/ And here's an amusing ScienceDirect example: https://www.sciencedirect.com/science/article/pii/S000632071... (I would have loads more specifically ScienceDirect examples except I learned many years ago to never link ScienceDirect PDFs because the links expire or otherwise break.)
