> an online service can't meaningfully claim to lack the connectivity needed for ID lookups

Partial connectivity outages happen literally every day. Most people don’t notice. Websites like “down for everyone or just me”, or uptime monitors that monitor from dozens of different source locations, exist because of this.

I don't think this addresses the point: if you can connect to a service, then laws like this will require them to make an ID challenge. If you can't connect, then it's a moot point.

The service itself can't say that it can't connect to you, because it's an online service and you're trivially connected to it.
