Even if they don't allow communication if one is down, you wouldn't need to turn them all on at the exact same time in order to get them working. They'd still be up and running and sending out signal to the other towers even if the communication network isn't accessible by the general public.

That's like saying all the telephone companies go down in Australia because Telstra has a problem. The other companies can still use Telstra's lines. The lines themselves still work. It's just the companies end which means people who utilise Telstra can't use their phone or internet. The same applies here. The towers still work with only three, you just can't use the services until all four are up and running.
