There's an update on linuxgamepublishing.com:

"As of Nov 23rd, we have a few more unforseen issues in bringing all of the sites back online, but we are working through these as quickly as possible. Some sites are back online, such as penguinplay, and you can also expect happypenguin.org to be back pretty soon. The LGP keyserver is back online, for those who rented LGP games and have been unable to play the rental versions. We have extended the rental periods for anyone affected."
