Hey all, we've been using R2 to store podcast assets for a few months using r2.dev and it's been working well except recently it stopped syncing. We contacted apple support and apparently they can't reach the XML feed stored on r2.dev. They get a "This site can't be reached" error. Has anyone run into that before?

r2.dev has heavy rate limits and poor caching, you need to set up a custom R2 domain name. r2.dev isn't for production

Got it, thanks!

Karew•5/7/23, 9:17 AM

There is no way to have the server do it, but you can list all objects and then sort locally, which may or may not be feasible

Karew•5/7/23, 9:18 AM

Alternatively, if you have references to your objects stored in a database or something, use the database to track that information

Karew•5/7/23, 9:20 AM

You could also technically sort by ""date"" if your objects have their date in their key prefix or something

TTubbyStubby2 I am actually creating an admin page for internal test builds of our app. I will...

Karew•5/7/23, 9:32 AM

I would say the truly best idea is to track uploaded files in a database

Karew•5/7/23, 9:32 AM

You could attach literally any other data to them that way

Karew•5/7/23, 9:33 AM

But if the date is part of the key prefix, you can list objects after a certain date directly on the API, you would not need to keep syncing

Karew•5/7/23, 9:33 AM

Because you could use start-afterstart-after

Just use PutObject if your file is too small for multipart

kian•5/7/23, 8:40 PM

If you must do parts then it also must be big enough for multipart

Unsmart•5/7/23, 9:05 PM

It is on here in a code comment: https://developers.cloudflare.com/r2/api/workers/workers-multipart-usage/

5MB is the minimum part size, except for the last part

But I assume this 5MB minimum size is pretty universal across all S3 compatible providers given that is the limit S3 sets.

Is there any plans to decrease the scope of what R2 API tokens have access to? Currently:

There are two access levels, read, or write, any consideration to make this more granular? What if my token only needs to Put items, but does not need to Delete anything? (protecting from mass deletion attacks)
Allowing us to scope what buckets each token has access to, I host a few R2 buckets, and a lot of them have to write to their relevant R2 bucket, it would be neat if I could scope them to be able to only write to the buckets they actually need.

Unsmart•5/7/23, 11:27 PM

Bucket scoped is coming soon I believe there was a tweet saying Q3 this year. As far as the first point not sure if that is currently planned.

Aiden•5/7/23, 11:28 PM

Great to hear about bucket scoping! Sounds good, is this the best place to leave product feedback for the first point?

Unsmart•5/7/23, 11:28 PM

Yes it is the team actively monitors this channel

For the first point, a presigned URL might work as well (although you’ll have to deal with expiry etc.)

Aiden•5/8/23, 2:40 AM

My concern isn’t with reading, my concern is with what each token can do.

Aiden•5/8/23, 2:41 AM

If my api process only needs to upload and never delete, I’d like that R2 token to be scoped down, to only do that (ie. Least privilege), it doesn’t need to read the bucket directly, thus I don’t think a pre signed URL would apply here

JJamesXXV Will R2 support S3 IAM compatible permissions in the near future? I understand t...

Sid•5/8/23, 10:31 AM

Bucket-scoped permissions are coming pretty soon, but IAM-compatible permissions aren't planned for now

Jay Townsend•5/8/23, 4:20 PM

anyone know how to get your bucket to have public access, as even on the r2.dev domain it is not viewable publicly and I have no idea what I am doing wrong

Hello, I’m Allie!•5/8/23, 4:21 PM

What do you mean? If you navigate to a file, does it show up? Like https://account.r2.dev/hey.html

Jay Townsend•5/8/23, 4:22 PM

Hello, I’m Allie!•5/8/23, 4:23 PM

No, I mean, if you replace account.r2.dev with your R2.Dev domain, and hey.htmlhey.html with a file in your bucket

Jay Townsend•5/8/23, 4:27 PM

so on my custom domain for it I get this which is the same thing that I get when I had it use the r2.dev url as well, do you want me to remove my custom domain while testing?

What is the path you are using?

Jay Townsend•5/8/23, 4:30 PM

@HardAtWork you mean the url?

JJay Townsend @HardAtWork you mean the url?

Hello, I’m Allie!•5/8/23, 4:31 PM

Yes. I don't need the hostname, just the stuff after the

Jay Townsend•5/8/23, 4:39 PM

@HardAtWork ah that did it, worked out what you are saying so if I give it the file name after the url, it then starts downloading the file. My assumptions was that I could just go to my custom domain and could view everything like this https://cdimage.kali.org/kali-weekly/ as an example

R2 just serves files, it doesn't do file listings. For that, you want https://github.com/kotx/render

thanks for your help and clearing up my confusion and thanks for that will have a look

cake•5/8/23, 8:06 PM

A few questions about R2:

What is cloudflares uptime guarantee for r2?
Are my buckets backed up into multiple regions with failover, or if the location that my bucket is stored in goes down, will my files go down as well?
