Hopefully you had a backup... I was on SH93 when it was moved to a new server. My WP site went down and never came back up. I put in a ticket and they fixed it pretty quickly (php.ini memory limit). For a few weeks after, I received many bounced email messages. I guess the new server had a dirty IP address. -- If someone refers to herself / himself as a "guru", they probably aren't.
They first told me that they couldn't find the backup. I have been very ill so my backup was from July 2013. I uploaded it and it worked but then they found my backup and restored it. I did notice that they changed at least 1 PHP setting so it caused a minor problem but I will find a work around.
