The mailing lists do seem to be gradually becoming operational again.
I gave up on my Guestbook ever becoming operational again and created a replacement, along with a snapshot of the entries that had been made up to Jun 2016.
The latest casualty, which had been working quite recently, was my LornaHenderson, WorldConnect database.
At the moment, and for the last few days, an update has been stalled after the load but before being made visible to the public again.
RootsWeb acknowledge problems exist but have no estimated time for a fix.
With that uncertainty and the usefulness of being able to point people to the BDM summary for all of the rellies and their connections I've quickly created* a, hopefully temporary, replacement
- the temporary replacement
- the permanent link - in case it starts working again - which it has 27 Dec
* by the newly available GedSite by John Cardinal. Using an existing GEDCom, the one the WorldConnect database is stuck on, it took less than an hour to set up and most of that was tweaking the wording of the main page and changing my mind about what other links to include in the menu.
