Apparently, it is not yet fixed? For:

{'definitions': [{'target': '2001:4b98:dc2:45:216:3eff:fe4b:8c5b',
'af': 6, 'packets': 3, 'type': 'ping', 'is_oneoff': True,
'description': 'Ping 2001:4b98:dc2:45:216:3eff:fe4b:8c5b from prefix
2000::/3'}], 'probes': [{'requested': 10, 'type': 'prefix', 'value':
'2000::/3'}]}

I get:

 Status 400, reason "{"error":{"message":"__all__: Your selected
 prefix is not covered by our network.","code":104}}"

But 2000::/3 is the entire IPv6 space currently allocated, all the
Atlas probes are certainly in it.
