well ip geolocation has nothing to do with bgp/routing though

ChaikaOP•5/8/24, 8:07 PM

only thing matters is their upstream/routes in that location/what Google makes available to them

ChaikaOP•5/8/24, 8:07 PM

it is spaghetti and confusing though lol

az•5/8/24, 8:08 PM

i dont think the interconnect is the problem

Hello, I’m Allie!•5/8/24, 8:08 PM

Doesn't it? Well, not BGP, but they can point you to a US datacenter if you resolve DNS with a US IP, no?

az•5/8/24, 8:08 PM

im making my request to cloudflare which is going to an american datacenter (which then subrequests back to eu) then back to me un eu

ChaikaOP•5/8/24, 8:09 PM

geoip/geodns yea, could happen. I remember when CF was talking about making machines share IPs and such but idk if that ever happened, I tested a few months ago and didn't see it

What plan is your site on?

HHello, I’m Allie!What plan is your site on?

az•5/8/24, 8:09 PM

free

Aaz free

Hello, I’m Allie!•5/8/24, 8:09 PM

That might be why? Free-plan sites are more likely to be rerouted. Though the amount of rerouting happening does seem a bit unusual

ChaikaOP•5/8/24, 8:10 PM

yea sounds your ISP -> CF issue, how are you determining the location you hit, just off the cf-ray response header?

Hello, I’m Allie!•5/8/24, 8:10 PM

Not so much that, more that if you try to look up a CF IP in MaxMind, it should always show US, even if it isn't US

ChaikaOP•5/8/24, 8:10 PM

that should just be for inbound anycast IPs and not the ones which connect to your origin/outbound

az•5/8/24, 8:10 PM

i normally go to man or lhr, but now im going to AMS or toronto/chicago/seattle

DarkDeviL•5/8/24, 8:10 PM

Depends on which IP you check.

Aaz i normally go to man or lhr, but now im going to AMS or toronto/chicago/seattle

ChaikaOP•5/8/24, 8:12 PM

there's sites you can use to see if it's plan based, there's another one but I can't think of it right now, can use https://debug.chaika.me/?findColo=true though

Had a thing up recently where every check I did was geolocated to SanFran

ChaikaOP•5/8/24, 8:13 PM

looks like you have no IPv6 but even free is going to AMS, doesn't seem too bad

CORS is not liking this page

ChaikaOP•5/8/24, 8:13 PM

oh is it broken by apple or the latest chrome stuff? rip

az•5/8/24, 8:14 PM

is this not just standard CORS ?

az•5/8/24, 8:14 PM

i will try a different ISP

Aaz is this not just standard CORS ?

ChaikaOP•5/8/24, 8:15 PM

oh a few of them are broken looks like, it should still display most of them

ChaikaOP•5/8/24, 8:15 PM

possible your ISP just had a fluke for a second with routing. If you're checking off the Cf-Ray that should be your input colo, but just to double check, you don't have smart placement on that worker right?

az•5/8/24, 8:16 PM

works fine on icloud private relay

az•5/8/24, 8:16 PM

must just be my ISP

I'm trying to create a worker to use as a service binding following the instruction in the recent blog post

javascript native RPC

javascript native RPC

but the worker fails immediately with the warning:

The entrypoint src/worker.js has exports like an ES Module, but hasn't defined a default export like a module worker normally would.

The entrypoint src/worker.js has exports like an ES Module, but hasn't defined a default export like a module worker normally would.

This is promptly followed by the error:

Uncaught Error: Dynamic require of "cloudflare:workers" is not supported\n

How to fix?

The Cloudflare Blog

We've added JavaScript-native RPC to Cloudflare Workers

Cloudflare Workers now features a built-in RPC (Remote Procedure Call) system for use in Worker-to-Worker and Worker-to-Durable Object communication, with absolutely minimal boilerplate. We've designed an RPC system so expressive that calling a remote service can feel like using a library.

Do you have a repo?

blindChicken•5/8/24, 8:55 PM

No but I can post code, it's only a few lines a this point.

Actually I think I just figured out the problem. If I include

it appears to work.

blindChicken•5/8/24, 8:58 PM

Hello, I’m Allie!•5/8/24, 9:01 PM

Oh... Yeah, that's because

wrangler

HHello, I’m Allie!Does your `class` have a `fetch()` method?

blindChicken•5/8/24, 9:09 PM

No. But neither does the code in examples of the blog.

Hello, I’m Allie!•5/8/24, 9:09 PM

Does your

include a route/workers.dev?

Hello, I’m Allie!•5/8/24, 9:10 PM

The example on the blog appears to be for a Worker that can only be called via Service Bindings, so it shouldn't have any routes/crons/queues, etc.

blindChicken•5/8/24, 9:10 PM

name = "worker-t"
main = "src/worker.js"
compatibility_date = "2024-05-07"
node_compat = true

name = "worker-t"
main = "src/worker.js"
compatibility_date = "2024-05-07"

Hello, I’m Allie!•5/8/24, 9:11 PM

Try adding

workers_dev = false

workers_dev = false

Hello, I’m Allie!•5/8/24, 9:12 PM

IIRC it adds

workers_dev

workers_dev

by default, unless you add a route

well ip geolocation has nothing to do with bgp/routing though
