The developers working on putting kernel.org back together have sent out a brief status update, mostly about the management of git trees.
"This new infrastructure will no longer have shell access to the git repositories; instead we will be running git using the gitolite web glue. Gitolite uses ssh keys to push into it, so we will start sending out new ssh credentials to the active developers who had kernel.org accounts before."
Git trees should go back online in the near future; everything else will take longer.
