First time out of the vault

For a story I'm writing, I want to put a destroyed government bunker somewhere, but to do that, I need to understand more about the Enclave. To my knowledge, these things are true:
1. The Enclave were the ones responsible for giving vaults the all clear signal
2. The Poseidon Oil and Navarro Enclave lost contact with other branches of the Enclave.
3. Somehow despite this, the President Eden was able to contact them from Raven Rock once they were defeated.
4. The enclave used poseidonet to monitor the vaults.
5. Cheyenne Mt, most likely housing one of the Enclave branches due to it's connection to Poseidonet, was completely obliterated according to Fallout 2 and Van Buren. it is the farthest area Poseidonet can connect to. Whether the network got severed, only extended that far, or was not fully shown is unknown.
So if that's the case:
How in fucks name did they loose complete contact with other government branches? Fallout 2 shows they are capable of radio communication, so Poseidonet being cut off doesn't sound like it would completely inhibit them from contacting their other branches. I find it very hard to believe that Poseidon oil rig was the only surviving Enclave branch. I mean did most of the control vaults outside the west coast not get the all clear signal and just say "fuck it, let's open anyway"? I'm not sure I understand why the story writers picked an oil rig to be the only surviving government installation.
