When I open Google Maps on a client PC that is behind a Large Scale NAT (LSN, Carrier grade NAT) the number of concurrent connections is limited to 15.
Do you have any solutions how to enable more connections when behind an LSN(CGN)?
I wasn't aware that these LSN's were being rolled out to the public yet. What a dissapointment.
Anyhow, Google Maps already tries to get around any concurrent request boundaries by splitting its map view over dozens and dozens of subdomains, as most browsers will only open a limited number of connections to a single domain.
If this is being controlled at a large NAT level, I doubt that there is anything you can do except submit a complaint to your ISP.
