Reading Now_Rudi 's article link, there is a bit more clarity on what happened. One of the circuits T-Mobile uses to send data traffic over had a failure. The way things were supposed to work is what I referenced above. ISPs connected over WAN circuits and the Internet backbone use a routing protocol called BGP (Border Gateway Protocol). BGP allows exchanges of route tables which tells routers at the ISPs how to direct traffic to its intended destination. Among the information exchanged by BGP is performance metrics and other data where the router can make an intelligent decision on where to send network traffic.

With the situation we're talking about here, that failed leased fiber should have been dealt with easily if everything was configured and working correctly as the router connected to that fiber would have distributed the network traffic appropriately to other network paths. So either something was missed by T-Mobile's engineers or someone F'd up and misconfigured their router(s).

It was the major fiber circuit that failed, turns out their fail safe backup also failed. This circuit is what controls their VoLTE. Basically is the voice only over LTE, which is why the calls only failed. So much for redundancy.

I switched to Spectrum, no problemos
