Не знаю, было тут или нет, но:
A search for «bzip2 source» returns bzip.org as the first three results. But it would seem that the owner of this domain has let it go, and it is now parked and running ads. So we no longer have an official home for bzip2. If a new repository or tarball does turn up at that domain, it should be looked at closely before being trusted
