You have 6.75 months to implement this before the current IP address no
longer works. Use idle time during holidays to plan when you will do
this change if your configs are frozen during holidays.

I did react with a sense of urgency when I first read the message, but
once you re-read it, you realise the timing and advance notice are
plenty sufficient.

Those one support can get a patch from their vendor or simple
instructions on how to edit their root.honts file to change an IP
address it in (or use dig to get the new one).

But probably can't make an announcement until everything has been approved.

Also, if you annouce something that will happen 1 year from now, more
people will just postpone the change and forgot about it.
