Increasing problems with geolocation/IPv4 access

This is a real and growing problem. I have some networks that have
experienced lengthy “no service” issues with streaming services such as
Disney+ due to this, and it took many customer generated complaints  and
“NANOG hallway level” type human back channel escalations to actually get
it addressed. And it still took months.

It would be Really Nice if the major streaming and other cloud service
companies actually had any sort of NOC that was reachable to open tickets
and resolve the issue. But that would require employing people with clues.

It is also sad how many orgs need a NANOG posting prompt to get anyone to
look at existing tickets on issues that get ignored for weeks or months.
