Hi Karsten,

The June 6 database is currently deployed and the June 13 database is the latest I could download from MaxMind. It looks like they broke something, and it seems unlikely that they'll fix that in the next database unless somebody tells them. Would you want to reach out to them and see if they can fix this?
did someone already reach out to maxmind?
If not: I would do it if you could send me the URL from where you downloaded the input file used by onionoo (maxmind page) and date/version (if it changed since the statement made above).
It seems they are using the first "descr" line they find as AS name.
