Google contact: apps vs IPv6 issue

[Max Tulyev <maxtul () netassist ua>]

Hello!

Could someone advice a good contact inside Google?

I'm operating a IPv6 tunnel broker http://tb.netassist.ua/

Now there are a number of complaints tunnel broker users can't access
Google Apps with the reason "We're sorry, but this service is not
available in your country".

IPv4 access to same pages from Ukraine is OK, and MaxMind GeoIP replies
our IPv6 network we are using in our service is "NetAssist, Ukraine".
