Is it just me, or did JISCMAIL decide to change their indexing system and
break all the links to old posts?
I'm not referring to the problem of the archives being "annualized," where links
containing information of the form YYMM are broken (the conversion renders
them as YY, with other information in the URL also changing). I have a
number of links stored to old posts, and even the links which were properly
annualized are now broken.
