What if the link is failed between master/slave

[Blason R]

Hi There,

I have bind Master server with me and slave is at other remote location. My
query is since I have opted for PUSH update from master to slave over
random port.

What if the link at slave is down and NOTFY message is not reached? When
will slave then pull the update?

Lets take an example

12.05 I updated the zone and reload it
12.06 xfer.out shows the update is sent but Internet link at slave is down.
Link is back at 12.20.
When will then slave receive update?
