Choppy network

Apologies if this is already a known issue. My internet connection is fine. Troubleshot every thing I can think of. Typically speeds 200Mb+. Network latency keeps spiking to over 300ms consistently (spans between 30 second intervals, and every couple minutes).Friends I play with here in the US have the same issue. Makes high maps and trials pretty unplayable. It’s solo and co-op play. Any new ideas on what to check are greatly appreciated.
