I no longer run a status update checker for this website. Those server statuses on the right are stale, and will probably not be refreshed by me anytime soon. You can also keep track of servers using toshley.net. That place not only keeps track of Battle.net and BNLS, but also Ventrilo, Minecraft, and other server software. I'd bookmark them if you haven't already.
Before 2012 really gets started, I need to clarify one thing: I hardly visit this site myself anymore. I probably visit once every 2 months now. The only reason I remembered this time was because I had the urge to check out the ol' Battle.net community.
That said, I wish the best of luck to those who still develop for the Battle.net community as a whole.
