    Investigating
    We have reports that some directories in netscratch are unavailable or intermittent. We are working with Vast to determine the cause. This is a new filesystem which is under heavy load for cluster use as well as migration from holyscratch01. We appreciate your understanding of these teething pains and will update you as soon as we have more details or resolution.
