We are currently troubleshooting a high load issue on this server which is causing FTP, email, and web services to be intermittently unavailable. We will update this post when we have more info. This may require a reboot in the next few minutes to sort things out.

UPDATED 4:45 PM ET: We have rebooted this server and our server management company is looking into the cause of the load issues. FTP, email, and web services are still slow and/or intermittent for now.

UPDATED 7:15 PM ET: The cause of the high load was determined to be too many mail connections for invalid users and from spam sources. We've added the Spamhaus Zen blocklist to our email server configuration to block most of these connections and the server has been stable since. We'll be monitoring this to ensure legitimate mail isn't blocked. Once we have determined this will remain in place, we'll send out an update with more details.
