Maybe it's because you're hitting AKL? Do you always get 520's with that or just sometimes? The fact that it has cf-placement seems like it's getting to SEA and wouldn't be colo-specific tho

C

Chaika•8/27/24, 9:53 PM

above, were you saying it only occurs with smart placement on?

B

Brett WillisOP•8/27/24, 9:55 PM

Yeah just confirmed, with smart placement turned off it functions normally (404). Obviously serving from AKL in my case.

B

Brett WillisOP•8/27/24, 9:58 PM

It's always 520 for me, but always via AKL colo in my case. It's a staging env so don't have other locations hitting. Did you get 520 from your colo?

Ok ok, so I'm using Cloudflare WARP. With WARP off my colo is SYD, and it works fine. With WARP on, 520.

B

Brett WillisOP•8/27/24, 10:12 PM

Just normal WARP (personal install, default settings).
Interesting why WARP only trips over here with the

workers.dev

workers.dev

workers.dev

workers.dev domain and not a custom domain route?
Anyway it seems more related to WARP, so sorry for over-hyping that "workers downtime issue".

C

Chaika•8/27/24, 10:39 PM

I tried reproing with WARP but I can't, wonder if it's related to akl

W

Walshy•8/27/24, 10:44 PM

let me hit it from akl

B

Brett WillisOP•8/27/24, 10:46 PM

Yeah I was just about to say, not sure it's completely a WARP issue. The 520 responses take ~500ms which is enough time go go all the way around the world (definitely beyond my machine and local colo which is normally 10-20ms away, SYD is 30-40ms).
And it's a combination of ALL these factors:

Smart placement ON (or served by SEA, not sure how to isolate but placement OFF + SYD works fine)
workers.dev domain (custom domains are fine)
Content-Length: 0 header present
WARP ON or AKL colo (haven't been able to isolate those two just yet)
