Load balancing adds 3s delay before sending request to upstream

I’m testing your Load Balancing and am experiencing a 3 second delay (to a static return 200) url. The delay seems to be on the request side, it takes 3s for the request to end up in the correct origin (with policy random).

However, I have no method of debugging this. I did a very simple test:

while true; do time curl "https://pool.DOMAIN/up?$(($(date +%s%N)/1000000))"; sleep 1; done resulting in:

I hope this is not to be expected - am I experiencing a bug?

I completely understand how this sounds like a PEBKAC situation but for me this is pretty important. To help debugging this I’ve collected a few RAY’s which I hope helps anyone give me a pointer of who’s to blame.

These requests all took ~ 3.1 seconds - for as far as I can see this is caused by cloudflare:

  • 5480271c3abcc82f-AMS
  • 5480273da9abc847-AMS
  • 548027579a7dc791-AMS
  • 548027718be872f9-AMS
  • 5480278b9844bf5a-AMS
  • 548027ac5e3dc79d-AMS

This issue seems pretty consistent.

These will only help support. You will need to open a support ticket in this case.

Thanks for your reply. I realize only cloudflare can use these. However - I don’t see any method of contacting cf - all their support pages redirect to this forum as the suggested support-tool. Am I missing something?
