As of January 5, 2011 and beginning with the 10.05 release, binary downloads are available at Sourceforge, too. This is to provide greater bandwidth and availability to users having experienced download problems with the canonical download site.
Please do note that the primary download location with the official, up-to-date releases remains at BerliOS here:
http://developer.berlios.de/projects/codeblocks
The binaries available here have been downloaded from BerliOS and re-uploaded to SF.
Thank you for your understanding.
