So that's the connection from Amsterdam then - can you try without VPN? 50 ms to FRA still seems like a lot

Ccodefrau So that's the connection from Amsterdam then - can you try without VPN? 50 ms to...

asp•8/4/21, 4:18 PM

Done

codefrauOP•8/4/21, 4:18 PM

32ms, that looks better

asp•8/4/21, 4:19 PM

So 32 ms is roundtime from my PC to FRA via CPH?

codefrauOP•8/4/21, 4:20 PM

yes

codefrauOP•8/4/21, 4:20 PM

the worker is in CPH and the DO in FRA

asp•8/4/21, 4:22 PM

Doesn't 50 ms seem seem alright then, if it's from my PC -> Amsterdam (VPN) -> CPH (Worker) -> FRA (DO)?

codefrauOP•8/4/21, 4:25 PM

I guess it is – I am spoiled by having the worker right here next to me

asp•8/4/21, 4:26 PM

I don't think there's anything to do about the ~10 ms latency added just to get out of the house

asp•8/4/21, 4:26 PM

this is COAX after all

asp•8/4/21, 4:28 PM

Anyways, thanks a lot for the help

codefrauOP•8/4/21, 4:28 PM

You're welcome

codefrauOP•8/4/21, 4:49 PM

Just to correct this - your connection from Amsterdam did not go via CPH. There is a colo in AMS, so that’s where the worker was.

codefrauOP•8/4/21, 4:49 PM

(the “via” item in the latency display is the worker colo)

asp•8/4/21, 4:53 PM

Ahh, alright - that's quite slow then, as I get 26 ms latency when running a Speedtest on the VPN. Cloudflare does peer with M247 in Amsterdam, right?

asp•8/4/21, 4:56 PM

Hmm, pinging

1.1.1.1

1.1.1.1

(on VPN to M247 in Amsterdam) gives me a latency of 28 ms, so perhaps the route between AMS and FRA is just slow for some reason?

yes, you pass the websocket request (with the "Upgrade: websocket" header) to the DO via

stub.fetch(request)

stub.fetch(request)

Kuririn•8/4/21, 9:15 PM

When I have durable object, let's call it xyz I must use fetch to communicate with it?
or could I call it's functions directly?

kenton•8/5/21, 2:09 AM

It looks like we have some sort of bug where some errors like this happen while we roll out an update to the workers runtime. We are looking into it. (FWIW, whenever you see "internal error" that means we think it's our bug, not yours, and the error has already been reported to our internal monitoring.)

Alright. Thanks!

Matt Silverlock•8/5/21, 1:11 PM

(I use Rollup on my own projects, and ES Modules are the way forward, especially with Durable Objects / Workers’ Modules API)

ItsWendell•8/5/21, 4:19 PM

Is it possible to know where in the world the durable object is?

John Spurlock•8/5/21, 4:32 PM

one way is to fetch

https://1.1.1.1/cdn-cgi/trace

https://1.1.1.1/cdn-cgi/trace

from inside the DO, and cache the colo field from that trace

John Spurlock•8/5/21, 4:35 PM

iirc module workers are now passed a

cf

cf

property on each incoming fetch request, so

request.cf.colo

request.cf.colo

is defined for the incoming worker request, but the

Request

Request

passed to your DO's

fetch

fetch

still does not have the

cf

cf

property (I just double-checked) - it makes sense since many of the custom

cf

cf

properties don't apply for the internal DO fetch calls, but a colo accessor (maybe on

state

state

?) would certainly be useful

ItsWendell•8/5/21, 4:49 PM

Yeah having the CF property specific for the worker would be great!

John Spurlock•8/5/21, 4:57 PM

in case you haven't seen it, check out https://where.durableobjects.live/ by @jedschmidt, a cool idea to find out which cf colos support DOs at the moment

It's on VPN to Albania - thought I'd populate the list some more

John Spurlock•8/5/21, 5:47 PM

it would be so nice to be able to send a worker request to a specific colo for testing this sort of thing

asp•8/5/21, 5:47 PM

How'd I not noticed that? I needed the locations of the datacenters for a project, so I scraped them off the statuspage then geocoded them.
