Lame reverse delegation at Sprint

I live on a tiny network at 208.31.42/24, which is SWIP'ed via my ISP to
me from Sprint. I do my own reverse DNS.

It looks like sometime in the last day or so, Sprint's DNS servers stopped
serving, which of course has broken my reverse DNS.
Sprint won't talk to me since I'm not a direct customer, and my ISP has
gone home for the weekend. Before I call them at home, if anyone from
Sprint is listening, could you make NS[123]-AUTH.SPRINTLINK.NET serve that
zone again?
