I really gotta make sure people aren’t uploading 2MB sized pfps though

PPaul I really gotta make sure people aren’t uploading 2MB sized pfps though

Hello, I’m Allie!•9/24/23, 1:21 PM

You can set a size limit on uploads with a presigned URL

PaulOP•9/24/23, 1:21 PM

I would then be forcing all my users to download them at that size then right?

Hello, I’m Allie!•9/24/23, 1:21 PM

Or well, you can ask them for a size, if it is larger than a few kb, reject it, and otherwise, sign it to that exact size.

PaulOP•9/24/23, 1:26 PM

That’s an interesting idea. Thanks

Just created a page for testing CF. Fast and nice, page up and running - but I can't find where is the data center(s) physically located that are now hosting, can I see that and/or influence it?

Not really, what are you looking to know?

Just wanting to be sure that my page is fast in both North Europe and South America, which are my two target regions for this specific project

Gotcha. Is it a static site? I think it’s generally safe to say any static sites are going to be handled quite fast by Cloudflare infrastructure around the world. If you have functions and dynamic components you could setup analytics to monitor and report back on speeds around the world

If you add a custom domain to the project it might just take a little bit to propagate

DDeleted User This is the result. But the question is if there is a way to make the pages.dev ...

Isaac McFadyen•9/24/23, 2:11 PM

You can set up a Bulk Redirect from the pages.dev domain to your domain. https://developers.cloudflare.com/rules/url-forwarding/bulk-redirects/

DDeleted User it is deployed globally as said

simpson•9/24/23, 2:18 PM

It is only in select datacenters though, I’m sure they’ll keep rolling out new hardware for Pages over time. nonetheless I wouldn’t lose sleep over it unless you have a reason to think your app/site isn’t performing well

kian•9/24/23, 2:21 PM

Pages is just Workers & KV, so the Worker is on every server globally and the assets in KV are stored in two central stores (NA & EU) & cached in the colo they are accessed upon request.

kian•9/24/23, 2:23 PM

I'm not entirely sure what you mean

kian•9/24/23, 2:24 PM

Where did you see that documented?

kian•9/24/23, 2:26 PM

Workers are definitely in all colos.

req•9/24/23, 2:26 PM

Performance isn't the only think I'm after, I'm trying to learn how CF pages actually works and what can I / can't I actually control. I've done projects where the actual physical location of hosting needs to be controlled and actually has to be limited

My clients include e.g. schools where form data cannot legally ever be even temporarily stored outside of EU. Thanks for the assistance!

Hello, I’m Allie!•9/24/23, 2:26 PM

If not, that might be why

simpson•9/24/23, 2:26 PM

Based on some quick testing we’ve done it seems like it is more like half, but that is somewhat anecdotal granted you can tail your functions and see what colo they serve from and we see a ton of traffic come from pretty far away

Hello, I’m Allie!•9/24/23, 2:26 PM

Some datacenters are paid only

Hello, I’m Allie!•9/24/23, 2:27 PM

But that’s not just Pages

Hello, I’m Allie!•9/24/23, 2:27 PM

I would note too that sometimes you may be routed far away due to bad routing at your ISP

Hello, I’m Allie!•9/24/23, 2:28 PM

?anycast

Flare•9/24/23, 2:28 PM

Take a look here to see why the Cloudflare datacenter you are routed towards isn't always the closest geographically: https://www.cloudflare.com/en-gb/learning/cdn/glossary/anycast-network/

For sure there are tons of variables but we’ve been watching New England traffic just out of curiosity for a few months on one of our projects and it virtually always goes to New Jersey and not Boston or New York.

simpson•9/24/23, 2:31 PM

Either way it’s super fast just interesting to see how it works, and I trust behind the scenes it is making the right decisions on routing, I think Cloudflare has earned that trust

Hello, I’m Allie!•9/24/23, 2:33 PM

But yeah, other than China(because reasons), every datacenter that you have access to is one that can run Pages and Workers.

simpson•9/24/23, 2:56 PM

That is quite impressive, I thought for sure that infra was still rolling out

Isaac McFadyen•9/24/23, 3:02 PM

Even at launch it was fully rolled out. Pages uses KV as a backend, which (as far as I know) was immediately rolled out to all datacenters because of the way it works.

kian•9/24/23, 3:06 PM

You don’t need NGINX to set headers, you can do that with the _headers file

kian•9/24/23, 3:19 PM

On top of Pages? Yes - you already get Cloudflare’s CDN
