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

ChaikaOP•8/27/24, 9:53 PM

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

B

Brett Willis•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 Willis•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?

B

Brett Willis•8/27/24, 10:04 PM

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

Brett Willis•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

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

C

ChaikaOP•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 Willis•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)

there is not, AE would indeed be the best path
