COM/NET/EDU nameserver changes

[Duncan Berriman]

I noticed this posting with interest as it's the first I've heard of it.

Whilst I can see the change could you explain it a bit more simply so I can
understand the affects. I understand how glue works but not entirely sure
how this change will cause failures.

We've already had one customer have a problem today - we don't manage their
dns I hasten to add, and its badly configured but it looks like they have
been hit by this change as their dns has 'suddenly' started to fail this
morning.

I'd like to understand more as to exactly what implications the change has
so I can explain to irate customers why its their issue and not ours!

Thanks
Duncan
