NOTE: the "NFO" QRQ MUMBLE server company that is being used has to this to say about the quality of their services: https://www.nfoservers.com/networklocations.php
"Most of our locations use pure INAP bandwidth. We chose INAP for its performance and reliability, and so have many other companies, including Microsoft, Alaska Airlines, Chase, Riot Games, and Sony. We buy directly from INAP, not through a reseller.
INAP gets its high performance by buying direct connections to many Tier 1 providers, such as Verizon, AT&T, Sprint, GTT/tinet, Verio/NTT, CenturyLink, and Telia, and choosing the best path to reach clients through a proprietary system called MIRO (tm) (Managed Internet Route Optimizer). MIRO makes frequent, automatic routing adjustments based on characteristics including latency, packet loss, and route stability, and it provides much higher performance than standard BGP methods."
