Please submit a ticket as soon as there is a sign of an issue. If there is something going on that we do not see, we would like to know right away. I looked at the logs and the only thing I saw going on today on that server was a PHP recompilation which affected a few sites, a reboot, and one guy whose site was suspended for overloading the server with his test scripts, which again are common place on the budget machines which attract many people looking to develop a site at a lower cost.
