Hi Christopher,

Thank you very much. We take about 24-48 hours to verify. This involves a series of checks backed by active 
measurement. To be honest, it is quite instantaneous. But the issue involves update cycles and cache purging. Usually 
it is around 24 hours. But sometimes like ASN type verification, you have to do much more extensive reviews but those 
are automated as well. So, to stay safe we say 24-48 hours.

If there is noise in the active measurement data, we will definitely fall back to geofeed. That is guaranteed. We are 
simply comparing the best possible data we have. We ingest a lot of data. And we pick the best.

We also use WHOIS country. In fact, for unallocated ranges, we use the RIR country. There is a hierarchy of fallback 
values that make it a good system.

We do not discourage geofeed submissions nor the geofeed. It is just that our active measurement data is generally more 
accurate, verifiable, and granular than what we observe in geofeed, on average. However, we do ingest geofeed and will 
pick it up when needed.

Time to update is not a bottleneck for us; users can submit their geofeed or correction via a simple form on our 
website.
