UPDATE - Topsite hosting program termination
http://www.osempire.com/community/showthread.php?t=12118
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.
