UPDATE - Topsite hosting program termination
After a lengthy outage the topsite server is back online, I suggest everyone begin migrating their topsite to another web host immediately.
The primary IP of the topsite server is under DOS attack. We do not have knowledge at this time if the attack is malicious or just a really busy site mass loading a button.php. We are in communication with the security team at the datacenter who has been working for the past hour to get us a prompt to work with. I'll post back here with updates as soon as they are available.
