The server maintenance of 2017-01-14+48hours has been completed. The maintenance consisted of moving repo.parabola.nu and repomirror.parabola.nu from proton.parabola.nu to winston.parabola.nu.
The DNS TTL is set to 24 hours, so it may take a while for the switch-over to become visible to some users; in the mean time repo and repomirror will still work, they will just be slightly outdated.
