So, how does this "persisted cache" mystically, psychically know that it is
right, and that the ISP's nameservers are broken/wrong? Maybe the ISP's have
made a more recent query than your nameserver, and received a negative
response. How can your nameserver know that this is *not* the case (unless it
has an independent means of getting the same data, in which case why bother
using your ISP's nameservers at all?)

Also, if the problem is that the ISP's nameservers are broken, why not just
get them to fix/upgrade their nameservers? Seems like that would help
*everyone* who is using those nameservers, rather than just selfishly kludging
things for yourselves...
