The Steam News Page
(thanks
Frans) has details on this week's update to the broadband content
delivery system. There's a lengthy list of what's fixed and changed, preceded by
this note about the update that includes word that Windows game servers are
going to require a manual restart:
We have released a game engine update
via Steam this evening. This release includes a number of additions and bug
fixes, including one which should clear up the remaining cases of the
authentication error people have been getting today.
Server admins please note that this release will require all game servers to
restart. If you run a server on Windows, you'll need to restart manually; Linux
servers will restart automatically if the server admin has enabled that option.
