It seems this is the closest I can get to a proper list: https://developers.cloudflare.com/ruleset-engine/rules-language/fields/standard-fields/#ipsrccontinent

which... is a totally different document from the worker docs...

its almost certainly the same list, the IP info comes from the same place and in the same format regardless if you read it in ruleset or workers

Do you want to trigger a Pages build from a worker or push code from a Worker to Pages?
For the first one you can create a Deploy hook and trigger a new build by calling the URL.

The gist of my scenario is that I want to call an API that returns a timetable. I only need to call the API once a day to grab the latest timetable. I then want to build a static page which includes an HTML table of the timetable that was returned in the API response. Finally, I want to push that HTML page to the corresponding route in the Pages project.

I have the first two steps down -- calling the API and building the page from the response. It's the last step -- deploying that page to a corresponding route in a Pages project -- that I'm struggling with.

I'll look into Deploy hooks. It sounds like that's what I might be looking for.

hey guys i am currently exploring different solutions to implement a machine learning model in python into my cloudflare stack. my first idea was to have a cronjob in my worker sending an http request to the python app but if i could get rid of an http endpoint i would do it, any suggestions? could queues be a good idea?

On the dashboard, if you make a real time logs, log, does it ever timeout or if you keep the window open it'll always show logs for however long it's open for?

Walshy•8/27/24, 7:35 PM

it should timeout after 6 hours

Walshy•8/27/24, 7:36 PM

but the dash starts to break down after a thousand or so entries, keeping it open for 6 hours i fully expect the tab to crash way before then

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 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?

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

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".

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)
