Has ping / tracert been blocked on 5g network?

Before yesterday (10/17/2022), I’ve always had a command prompt window (MS Windows) up running a constant ping at 3 second interval - so I can tell when the network starts to degrade or just stops responding (which has become very frequent in the last few months).

As of yesterday morning, both ping and tracert commands consistently fail.  As in no longer any response.  So it appears the ports used for those commands are now being blocked on the 5g network?  

I have a 5g phone on Tmobile, and I see the same result.  On 5g with hotspot turned on, with computer connected, ping and tracert fail 100%.  If I force the phone to use LTE and stay off 5g, ping and tracert start working again.  Don’t really understand why Tmobile would block such a basic network analysis command.

This is in downtown Scottsdale AZ.  As a sidenote, service on the 5g network degrades consistently  every day after about 8am, and usually is consistently bad all weekend long.  Works great before 8am most days.

I have been battling with this for months in the Phoenix AZ area. My other phone is AT&T and they are also blocking ping/trace. 

Oh, I also have the T-Mobile home internet router and ping is blocked for wired and wireless devices connected to the router.

The blocking/failure of using the ping utility seems to vary from one location to another. Here in east TN we had a period of time when it was failing to work but now it does. More than likely there is a configuration parameter in place to block ping packets. T-Mobile can run it down if they are motivated to do so. They may not be aware of the behavior in that location. Once they had enough complaints here they addressed the behavior and now it seems to be resolved. Well, it works here. You might try doing an IPv6 ping vs the IPv4 ping and see if there is a difference in behavior from one to the other. It might take a call to T-Mobile support to possibly get headway.

I use pingplotter (pingplotter.com) and it has always been working for me.
