NextDNS significant performance issues

I live in St Louis and am experiencing NextDNS performance issues from Spectrum Home internet via DoQ.

My mobile device is also experiencing issues via Android Private DNS on T-Mobile.

I am running continuous pings to 8.8.8.8 successfully, but NextDNS 

I've been using NextDNS for years in 3 states and no issues until yesterday/today. Provided diagnostic below.
