I posted a update at the support forum, i'll paste it here:
"It should be up again.
Please feel free to test:
http://hegre.thumblogger.com/
If this blog appears then you will soon be able to reach your own blog and thumblogger.com site and control panel.
[edit] another good thing to watch is your statistics counter, take a look at it and see that more and more traffic is coming to your blog.
Please note: other people can view your blogs, that is why i hinted that you should take a look at your stats counter because this will prove that other people can view your blog.
You might wonder why you can't view your blog but others can, that is likely because your ISP (the company that connects your computer with the internet) doesn't react as fast as other ISP's to IP changes. (it's a bit technical) This process might be speed up by closing your browser or restarting your computer, but it mainly depends on your ISP."
