We were performing a routine security update when the Squid 19 server became unresponsive. We are currently working with our data center to restore all services as soon as possible.
UPDATE 12:06pm PST: The server is back online.
UPDATE 2:32pm PST: Due to problems with the kernel changes applied we will be reverting this change and rebooting the server once more. We hope to have the server back up ASAP.
UPDATE 2:43pm PST: The server is back up once again and maintenance is complete.
