Sorry if I'm a bit slow responding - work is hectic and the work/life balance is a little skewed!

I'm using a TSIG key and DNSSEC mechanism to update the zone - I've been using the zytrax books as reference:

https://www.zytrax.com/books/dns/ch7/xfer.html#allow-update

But as the names are dynamically updated, there is no change to the Serial number

This is what I thought of too. To phrase it a bit differently, when I
first started doing similar to you (not dynamic DNS, but a 'hidden
master' with my VPS/A&A as secondaries which actually get used by
machines on the internets), I initially was forgetting to update the
serial sometimes. Then the NOTIFY gets sent, but the transfer doesn't
happen properly because the other side thinks there's nothing for it to
fetch.

Maybe that's what is happening here too.

Cheers,
