> "We have a customer at this address and the min/avg/max download speed their connection has had this year was X/Y/Z" Not even that. The data could be "With no more than a 1-hour router installation on premise, we (ISP Alpha) would be capable of serving this address at 500 Mbps download speed with 99% uptime, 800 Mbps down with 95% uptime, and 1 GB Mbps with 80% uptime." Ditto for upload speed. That's not customer information. Whether anyone at "this address" actually uses ISP Alpha internet right now doesn't matter until the customer disputes the advertised speed.
