Have the URLs of non-English LT sites changed?

I've been using the Welsh language LT site, which uses (used) cym in the URL instead of www.

Now I find myself on www, having been asked to choose a language, with the labels now in Welsh. Is this happening across LT language sites, or have I been caught up in something? Many thanks.

You might want to check into this thread, because Tim is making changes.
