We are currently experiencing networking issues with some of our MySQL servers in the Alchemy datacenter. If you are getting a ‘Lost connection to MySQL server’ error on your site, please keep an eye on this post for updates. We don’t have many details on the cause of this error, but our admins are working on the situation now.
And now you know as much as I do about it.
