Hello all,
I got an official answer from sales representative:
"Currently, Meraki products are not officially available or purchasable in Russia due to government regulation: they required Meraki datacenter being physically available in Russia, but currently, they aren't."
There could be a workaround, but it isn't so flexible: buy a Meraki outside and deliver it to Russia (in some way). If a replacement would be needed (due to some damage, for example), then sent it back, replace it, and re-send.
Bye,
Luca
