Not grandparent, but browsing through my private notebook for potentially breaking links, eg:
http://lesswrong.com/r/discussion/lw/deg/less_wrong_product_service_recommendations/6yry ← which is one specific advice (and a good one at that) vs https://www.lesserwrong.com/r/discussion/lw/deg/less_wrong_product_service_recommendations/6yry ← which is 404. This actually do have a high impact both on other sites linking specific comment threads, and by extension, on SEO in general (linked page with content changed to empty).
( Relatedly, https://www.lesserwrong.com/non-existing-page returns HTTP 200 instead of 404, which is more wrong, than http://lesswrong.com/not-existing-page )
Quick note (partly for my own reference as I check which of these we have fixed)
The first two links look they got fixed by Habryka’s recent patch.
I haven’t looked into the final issue, thanks for pointing that out.
