T-Mobile in Minnesota
We are seeing T-Mobile customers changing source IPv4 addresses constantly
in the Twin Cities Metro Area at least and at a very high rate, seems like
their Carrier Grade NAT is overloaded or at least not behaving well.

Is anyone else seeing this?

Thanks

The problem was on our side, our application people were using IP-based
persistence on their load balancer; they changed to cookie-based
persistence, and all is well.

Thanks
