Sometime this morning, our core fileserver started having some disk issues. We're working on figuring out what exactly went wrong and fixing it, but in the meantime, the OCF is effectively down (no lab, no SSH, no web, etc). We'll post updates as we have them.
UPDATE: The problem seems to have been fixed, though we're still not entirely sure what it was. We'll keep working on it throughout the day. In the meantime, though, the OCF is back up and ready for business.
