This may be caused by unusually high system load due to account abuse or network traffic. If you continue to have an issue, please post back and I will request an admin troubleshoot the problem further.
I can confirm the same problem (on starka). I posted in another thread as well, which seems to have been pretty much forgotten about. It started with the disk-space upgrade. CPanel loads fine, cpu usage isn't high, but any pages load slowly.
I have just visited your website and it seems to be loading fine. I am now going to close this thread to mark it as resolved as your original problem is solved and you have not posted a response in over 48 hours. If you need more help or have any additional questions, feel free to create a new support request.
