The problem with the Server Upgrade solution is that new players aren't going to know that. Heck I didn't know they were craftable at first myself until a friend told me about it, and I've been playing this game since.... I'm not sure which version. Back when the base only had one floor to it (not counting the one room down the ladder). And even with server upgrades the wait time seems to still be based on RNG. I've had a satellite with three upgrades still running into multiple errors, I've had a satellite with no upgrades only take like four tries to finish.
In any case having the player just wait around now for a semi-random amount of time feels far less engaging than the old Hashtag system. I feel like this new system could work better if there was some form of player interaction involved apart from just typing "sv.request".
