Ping issues between 8pm to 11pm every night.

Regularly experiencing high ping every night for at least one hour between 8pm and 11pm. There is no issue with my equipment, this happens even wired in and I have tried multiple applications, devices, cables, etc during impacted times (ping of up to 5000ms). Tried troubleshooting with an agent, they reset my connection twice without warning and the second time I could no longer connect to them.
