a voice recording was made, let me ask if it'll get posted somewhere

Is there an HTTP header that I can use to tell browsers that they shouldn't be requesting the resource, ever?

I was thinking of adding:

Access-Control-Allow-Origin: asdf.invalid

Access-Control-Allow-Origin: asdf.invalid

Since .invalid.invalid is promised to not exist, right?

What other headers can I use to block a browser from accidentally sending a request?

Should look into CORP I believe:

What makes you think it's wrong? That could be the actual speed from Cloudflare with your ISP.

What about fast.com?

whats the telecom?

dave•5/23/23, 9:00 PM

My ISP at home sometimes likes to drop packets like crazy to Google and Microsoft services during working hours.

nomaxx117•5/23/23, 9:01 PM

could be that they are messing with the traffic, let me ask someone if we know anything about DT

Chaika•5/23/23, 9:01 PM

silly question, but you're letting it finish right? speed.cloudflare.com does a bunch of tests going up in size, gotta give it a solid minute to finish, unlike fast.com

nomaxx117•5/23/23, 9:04 PM

could you DM me the output of https://cloudflare.com/cdn-cgi/trace ?

nomaxx117•5/23/23, 9:07 PM

you might find this illuminating: https://blog.cloudflare.com/eu-network-usage-fees/

There’s an important debate happening in Europe that could affect the future of the Internet. The European Commission is considering new rules for how networks connect to each other on the Internet.

nomaxx117•5/23/23, 9:08 PM

forgot that DT has a bit of a history of things

nomaxx117•5/23/23, 9:08 PM

i can check a few more things off of that trace info, but its probably safe to say its your isp

nomaxx117•5/23/23, 9:09 PM

FFelix alright, thank you.

Chaika•5/23/23, 9:10 PM

out of curiosity, what speed do you get downloading https://r3.chaika.me/200MB.zip ? (just a random test file in R2, cached in fra)

Chaika•5/23/23, 9:12 PM

If you're using Chrome you can just go to chrome://downloads/ and see the raw speed

Chaika•5/23/23, 9:12 PM

your connection should be slow enough that it won't finish in time lol

Chaika•5/23/23, 9:12 PM

(Firefox shows you the speed right away,

firefox)

Chaika•5/23/23, 9:14 PM

lol so same speed, I was just curious if it could be the test bugging out. iirc it's ran from Workers though, so probably not too likely

Chaika•5/23/23, 9:15 PM

~~that is your true speed to the something in the cache of fra~~
actually fra is a multi-colo pop, meh, even pulling from R2 should be faster then that though. I get ~50 MB/s on my vps in germany to it uncached

Chaika•5/23/23, 9:19 PM

yea I've heard things before about the ISPs there being meh and charging for peering/other fun stuff

Chaika•5/23/23, 9:20 PM

so much so that some local german services will sometimes get routed out of the country and then back in because they charge for peering
