Where is immutable data stored?

Core Blockchain
#1

I stored some immutable data in the name devname0.id with the data_id “test”.

I see that the hash of the immutable data is stored in the name’s zonefile:

$ORIGIN devname0.id $TTL 3600 test IN TXT "#9724c1e20e6e3e4d7f57ed25f9d4efb006e508590d528c90da597f6a775c13e5" _http._tcp URI 10 1 "https://www.larrysalibra.com/blockstack-data/devname0.id/profile.json"

When I retrieve the data with the CLI, I’m given the value:

blockstack get_immutable devname0.id test

{
    "data": {
        "key": "value"
    }, 
    "hash": "9724c1e20e6e3e4d7f57ed25f9d4efb006e508590d528c90da597f6a775c13e5"
}

Looking at the code for the CLI:

it appears that it’s loading the data from the local user database. If it’s not found in the user database, it looks for an immutable data url. I don’t recall setting that url or uploading the data anywhere. Where is immutable data stored?

#2

I tried to lookup up the same immutable data test on name devname0.id using the blockstack explorer server’s cli instead of the machine with which I ran put_immutable on, and it is unable to retrieve the immutable data:
