12:26am PST – Our squid16 server is down and we currently looking into the situation.
12:52am PST – The server has been rebooted, but is still not responding. We are continuing to investigate.
1:10am PST – The server was rebooted a second time and is now functioning normally.
Update: It turns out the problem was related to a bad network switch at the data center that had to be reconfigured.
