What a good new for the local NOG
community [1][2]!

Please are you willing to take time to
carefully document your usecase? so
that it could be really helpful to push
IPv6 in that small country. The cmNOG
will be glad to volunteer at least on
publishing/sharing your great #IPv6Story :-)

...happy eyeballs [3]?

All my encouragements to your team.

:-) Looking forward to also read you on
appropriate local public mailing lists [1].
