It’s SUPER common for all of the carriers on a cell site to share the same common backhaul path. And I can tell you from personal hands-on experience the majority (90+%) of cell sites in the US have simplex connectivity.

I'm familiar with the island, it's it's puzzling that the major 3 cell carriers would accept a single point of failure like that, you would think they had microwave backup at minimum. Maybe it was a generator issue. 

I'm sure a few cells burned but there are over ten on the west side so they didn't all burn. 

Feet on the ground are reporting they brought in at least a few COWS (cellular on wheels/portable cell site trucks)

To put it into perspective: there are exactly TWO roads that can get
you from Lahaina back to Kahului and the airport. One of them is a
narrow, cliff-hugging single lane road that is more or less paved.

Though I am curious about the Paniolo cable landing in Lahaina. Did it
survive? HICS and HIFN land in Kihei instead, right?
