Hi Tom, I sincerely apologize for this mistake. We used an existing dataset that associated ASNs with providers, along with some manual checks and additions. We validated the results for the providers we were initially focused on, but unfortunately, Yahoo wasn’t part of that initial validation. When we later added it, we didn’t go through the same verification process. So, while our dataset included a set of ASNs for Yahoo, it was missing the key one you pointed out, and we didn’t catch the error.
We’ll be implementing additional checks across all providers to improve our accuracy, but we can’t guarantee that every ASN will be captured. We’ll also update our figures and are happy to incorporate any fixes that others flag. Thanks again for bringing this to our attention!
