Due to problems with one partition, copr-dist-git machine stopped responding and we had to reboot it. But it got a different IP so we had to change the DNSs records, and now we are waiting to get those propagated. Should be ready in about one hour:

We have to fix several things in our stack to not repeat this situation next time. Sorry for inconvenience,

Pavel
