The format of this list has changed, from a plain text file with a customer schema to JSON. Adjust our routines accordingly to make use of this list again.

It would be nicer if you didn’t do so many things in one line, because it will get difficult to catch the correct exception.
I believe that this should be split into the json.loads() operation where you should catch any JSON decoding issues. This would make it clear that some kind of download issue or similar has happened.
Fetching the “asn” field should be a second step, because an error here means that you have received a valid JSON object, but the format has changed.

Yes, that makes sense. I'll submit a second version of this patch.
Having the json.loads() operation and the extraction of listed ASNs separated carries the benefit of being able to extract the AS's name as well. I was thinking that we might want to update the autnums table accordingly, if it does not contain the AS already.
This would allow us to have names for ASN-DROP'ed ASNs in the LACNIC space. However, there are only two listed at the moment, so I'm not sure if this is worth the effort. But then, having nothing is better than having nothing at all. :-)
What do you think?
Thanks, and best regards, Peter Müller

I believe that this is a good idea, because potentially the ASN provided might be fake, and debugging is probably getting easier if we are looking for the same thing.

Agreed.
