You're not missing anything - those are all real problems! We've done a lot of work to overcome many of them, and others are active areas of research and development for us.

We do scan and traceroute all IPv4 and (known) IPv6 space, once a week, so our measurement data can be out of date by at most a week. We have other signals that an IP might have moved within that timeframe though.

We definitely don't have a significant share of total internet traffic - but we do get 6BN API requests a day.
