Random drops / 3 sec response time

There is this issue going on for weeks now, at random time intervals the response time for pages go from around 0.15 seconds to 3 seconds causing huge slowdowns and drops in traffic because of it. My own nginx requests log show the exact same as cloudflare's panel. Issues appear to be L7 at CF

I have spends day debugging, and in short this is what i found out.
1) It happens to all my sites across cloudflare, across all datacenters in the Netherlands.
2) I tried various things such as disabling tiered caching, moving firewall rules with no changes. There is also no changes in WAF logs or any ddos or such going on.
3) Bypassing cloudflare and going directly to the server solves all issues during the downpeaks.
4) This is not an issue with origin.
5) I have made a ticket #3193135 but its been EIGHT DAYS with NO RESPONSE.
