I am not sure about that. Getting to know the timeframe which people
have and if they are interested at all helps a lot when determining a
date for such an event.

So it is neither the 11th, nor the 12th nor the 13th :)

I guess weekend is out of the question anyway?

I then propose Monday, October 18th(!) at 20:00 UTC,

It is up to date (well, from now on it will, at least). One problem is
that the data sometimes really is off, so machines in the UK are
flagged as being in the US or Canada and things like that.

Second: It doesn't help in cases when you'd like all the machines in
your DC to hit the mirror which also is in that DC. If you aren't the
admin of all of those machines, using the same AS or /16 would be
great. And that is what our mirroring system cannot do.

The problem is that we can *only* do GeoIP. The granularity of that
isn't fine enough at times (see above or other examples in this
