[Clug-tech] Update frequency of Shaw DNS?

[Martin Glazer]

This is a timely topic as I just had to make some changes to my DNS  
this morning.

I use dyndns for a number of hosts and I made a change this morning to 
one of them. I found that within a few minutes, the Shaw DNS servers had 
been updated. Same with Telus DNS servers (I have clients using both).

I was surprised by the speed of the updates...
