Thank you for leting us know the exact time of the rollover.

I wanted to question how did you chose it?

I'm asking this because it doesn't seem to be the best pick. Ok, I now that
probably the are no good pick's for this operation...

I'm criticizing the hour choosen because, 1600UTC, because it will be
1800CET and most of the network engeniers will be out of the office or
going out, and also most of the internet users will on their way home.
So if anything breaks in a network (He hope not) we would have a very high
number of users calling the Telco callcenters sayng that their internet is
not working.

According to APNIC statistics Europe is one of the areas of the world where
there are more resolvers with validation on.

Thank you and best regards,
