Is Mender.io accessible in the government cloud?
What do you mean by the question? In general, the Hosted Mender instances are located in either US or the EU, on public cloud offerings so they are publicly accessible.
If your use case is tied to operating inside a specific cloud that does not allow outbound connections, then you can set up an on-premise instance there. In that case let us know and we’ll get in touch to discuss details.
