Since my host upgraded its version of Apache, visitors to my blog archives (most of whom come from searches) have seen raw HTML rather than cooked webpages, because the filenames don’t end in .htm(l). So I’ve republished the archives (now daily, for speed’s sake, rather than weekly or monthly) with new names, and corrected the internal links to match. (I’ve even repaired a lot of broken links to Blogspot.)
Maybe someday I’ll learn enough to intercept requests for the old archives and translate them.
This became moot a year later when I converted from Blogger to WordPress.
