Yahoo is shutting down its Groups website and deleting all content

I just saw this announcement today which, if true, will mean that hundreds, if not thousands of genealogy mailing lists will be cut off with very little notice. Yahoo is shutting down its Groups website and deleting all content:

Yahoo (owned by Engadget's parent company Verizon) is phasing out one its longest-standing features. The internet pioneer is closing the Yahoo Groups website in a two-phase process that will effectively see it disappear. You'll lose the ability to post new content on October 21st, and Yahoo will delete all "previously posted" material on December 14th. Users can still connect to their groups through email, but the site will effectively be vacant. All groups will be made private and require an administrator's approval. If you're at all interested in preserving your history on the site, you'll want to download your data either directly from posts or through Yahoo's Privacy Dashboard.

It should be borne in mind that Tahoo! got into the mailing list business when it took over something called E-Grous, which ran public mail servers. If they were concerned about their customers they would give them enough notice and time to possibly arrange for alternative mail servers. As Yahoo! took over E-groups, so other servers could possibly take over some of the lists hosted by Yahoo!. But if they close it down with such short notice I will certainly be removing my Yahoo! Id, and will have nothing more to do with any of their services in future.
