The secure tier is provisioned with 32GB data volumes, but we're pushing the limits on that. Although the amount of data we use could be reduced, I'd rather just put bigger volumes on the hosts today since some of the reductions (e.g., to Harbormaster build data) are complicated future things anyway.
This is happening shortly (e.g., in the next couple of hours), so this server will be read-only or unavailable for a bit.
