@rei_vilo good suggestion. This is something we might consider building; it would require some effort to design and build. One practical consideration around this is that we release new firmware versions constantly, and keeping the offline compiler up to date could be a challenge. This is just one of potentially several factors for us to consider in building this as a feature.
On a higher level – there’s a tradeoff between the many things we are building and maintaining vs. the number of hours in a day for each of us. We would love to build all the things, but we are a constrained team! Thanks for your understanding as we continue to implement and support lots of stuff.
In the meantime, have you tried a DNS workaround to see if you can get past this issue? Its worked for several of us. You could use this as a starting point for DNS alternatives: https://www.opennicproject.org/nearest-servers/
