Controller still offline. No watering occurred today. I’m pretty frustrated. 
I emailed this thread to support, who sent back some information about “Zone Current Start” values, but not enough to clarify the impact of the situation they’re describing:
We have the current reading for the zones (Atrium Garden Drip Zone Current Start: 690, and Backyard Drip Zone Current Start: 664) on our end and yours is showing a little bit higher, however, not that high.
Both of these zones have existed for several years, and shouldn’t have been impacted by the new zone added before these problems started.
Does anyone have any information regarding how I might be able to test this value myself, or experience with values that are “a little bit higher, however, not that high” causing the controller to fail initialization in such a way that it never tries to reconnect to WiFi?
Additionally, if Zone Current Start values being out of range can cause the controller to violate one of its key features - watering even while offline - would it be possible to expose those values to customers and front line support so we don’t collectively waste time blaming the wifi network? If it was possible to view this value, I’d have certainly had the irrigation contractors I had out recently to add a zone look into it!
