Nothing vague about it, as they mentioned what was going on in the various Follow-up posts. The maintenance was to extend the lottery period while they continue working on the 0 bug issue, which, as mentioned in Follow-up #3, could be a number of business days because they want to replicate the errors, fix them, then verify the fixes. I was hit by the bug so I get the frustration, but it would be would silly to hold another lottery while working on preventing the bug from occurring again.
