2021-09-27 19:05 PST: mirrors are back up, this downtime should be resolved. If you notice any issues using our mirrors please reach out to us at email@example.com.
We are currently (9/22) running emergency maintenance on mirrors.ocf.berkeley.edu. Due to an earlier drive failure we've had to replace the drives. We expect the mirrors server to be down until Monday, but we will keep this blog post updated.
