Loading time issues with sp-studio.de?

Since yesterday around noon the http://www.sp-studio.de main page (including the blog and contest page) are loading extremly slow for me. So slow they sometimes just end up in showing a blank screen.

But not every time... sometimes they load as fast as usual. And Jareen did not notice this yeesterday.

The Forum and other Websites are not affected for me, so I am not sure if it's a problem with my browser or with the website.

Is anybody else experiencing these loading problems?

If you notice something please report it in this thread so I know it's not just happening on my own computer. Until then I will just hope it's not a website issue.

This might not be connected, but... since yesterday I have often problems when I want to reply to a topic. I get the error message: "The server encountered an unresolvable problem, please try again later." and a long ID.

Do you experience the same problems?
