Fortunately, since TrueCrypt is open-source, a group of independent developers have hosted the code-base and are hosting it at TrueCrypt.ch within Switzerland. The TrueCrypt.ch site isn't yet calling their code-base a fork but are mirroring it for now along with the releases for all major platforms. The site reads, "TrueCrypt.ch is the gathering place for all up-to-date information. If TrueCrypt.org really is dead, we will try to organize a future."
Additionally, "Currently it is very unclear what really happened. Was it really just the end of a 10year effort, or was it driven by some government. While a simple defacement is more and more unlikely we still don't know where this is going. However the last 36 hours showed clearly that TrueCrypt is a fragile product and must be based on more solid ground. We start now with offering to download the Truecrypt file as is, and we hope we can organize a solid base for the Future."
The developers organizing this TrueCrypt.ch project are Thomas Bruderer and Joseph Doekbrijder.
