NTT latency problem started early-evening today (Eastern Time).
Spectrum Internet is fine until it hops off to NTT in Atlanta.
>200ms ping (usually <100).

Fixed by using VPN (Nord) and connecting to a few different locations until I got a connection with no packet loss.

Spectrum routing through Atlanta, then to NTT drops many packets and causes major latency and gameplay issues. VPN to Charlotte seems to be better (125ms ping and no packet loss)

I hope this helps someone.
