High ping to whole internet

We've been experiencing high latency in games and get 400+ ms pings even to google.com, 1.1.1.1, etc.  Modem upstream and downstream power levels are good, and so is S/N ratio.  Modem logs are clean.  Ping to my modem is 1ms or less so it's not my network.  The connection is hard wired.  

What could be going on?
