indeed. my first rule of 'planned' DNS changes: lower refresh to minimum
acceptable. then when I'm sure everything works, up it to my defaults.
And , btw, if you hear of those DNS hosters that tell you they have
"instant propagation" , make sure you read the very very small footprint
that says "within our network". i.e., DNS is a game where all DNS
servers play along...or not ;)
