ISP Problem: High Latency with HIGH TTFB ! Workers served from other End of the Globe!

All my Workers are served from LAX.
Here is a example of the Header Request

CF-RAY: 5f93f31fddffe7a8-LAX
cf-request-id:06b05647e40000e7a867aca000000001

Before it was Frankfurt or Zurich

Here are traceroutes.
Strangly the routes change nearly every minute.
One time it goes over Frankfurt other time over a Swiss ISP
