I have some serious hosting problems as many of you found out. My domain and apparently subdomain http://gamedev.kproject.gr timeouts quite often. Appears to be some routing issue in the hosting servers. Has anyone of you had any problems like this. It appears i will change hosting provider really soon.
no timeouts here 
seems they solved the problems
Works here now 
I checked your link several times the last few days, seeing the problems others had. and it always worked for me. (Sadly, I didn't have time yet to try out your cal3d node, however).
