Hello R2, I am trying to track a hang/

Hello R2, I am trying to track a hang/slow down when I download a lot of files very fast. I use R2 to hold data/artifacts for ML training, and before training download a few hundred GB per worker from 16-64 workers. What I see if things seem to work fine downloading on one worker, but when I ramp it up some files hang or download very slowly (O(kbps)). I use S5cmd with parallelism, so total download can be ~300 Gbit/s and 300+ class b requests per second. Is that something that's likely to get throttled?...

I recently used slurper tool to move

I recently used slurper tool to move data from S3 to R2. AWS shows me 2.73 TB but cloudflare shows me 7 TB for the bucket. I am using a script to get all the files and the size and it is showing 2.73 TB which is matching what I expected. The dashboard seems to be way off and I am worried this will impact billing. The initial move had some errors (10% files could not be moved) and so I ran it again 2-3 times with skip files turned on and it only attempted the error files in future migrations. I also set it to remove failed multi-part uploads within 1 day. Anyone else facing this?...

I'm getting a ClientError exception when

I'm getting a ClientError exception when attempting to upload files bigger than 500MB to R2 via the s3api put-object command. Only instructions I found online was to use the CRC32 checksum algorithm, but I'm getting the error anyways. For smaller files it works without a problem. Uploading to S3 also works. The error simply says: ...

Internal error when uploading

I tried to upload a file to an R2 bucket using AWS CLI in GitHub Actions (GitHub-owned runner), but it fails with internal error. The same command runs fine in my local environment with the same access key. Details. The command is like this:

aws s3 cp "$filename" "s3://$BUCKET_NAME/$filename" --endpoint-url "$ENDPOINT" --acl private

aws s3 cp "$filename" "s3://$BUCKET_NAME/$filename" --endpoint-url "$ENDPOINT" --acl private

I tried the command with and without --acl private, and it did not make a difference. ...

Hi!

Hi! I'm trying to migrate a bucket from Scaleway to R2 and I keep hitting the "The connection cannot be verified. Check the following and try again." message. As far as I can see I've set all the parameters correctly (endpoint, bucket name, API keys) and the source bucket is set to Public. Does anyone have any prior successful experience with Scaleway -> R2 migration and if so, is there anything special that needs to be done?...

Hi everyone!

Hi everyone! We’re running into a weird issue with our video uploads on Cloudflare R2, and we could use some help figuring it out. We’re using Vue.js v3 on the frontend with the Uppy library for uploading files, and Django v4 on the backend with Boto3 (v1.34) to handle all the R2-related API stuff. We’re creating presigned PUT URLs on the backend to upload files directly to the R2 bucket from the client side (browser), including multipart uploads....

Hi, i have a question about the rules

Hi, i have a question about the rules and R2, I have a rule that redirects all traffic on my domain. But i want to setup a custom domain for R2 storage and i want that the traffic on this domain is not redirecting, but showing the content. Will this custom domain thing overwrite the CloudFlare Rule?

ChatGPT - R2 Lifecycle Deletion Behavior

Funny, cause Chatgpt was the first I asked 🤣, the answer wasn't that reliable as you can see in our conversation. That's why I asked here which I almost never do. https://chatgpt.com/share/67b7f4a7-e994-800a-8728-938ba08f5dcc But thanks for trying...

Remove R2 compatibility notes on sdk cli...

It appears that the recent incompatibilities between the S3 libraries and R2 were resolved but that doesn't seem to be the case for me. I've posted a note here: https://github.com/cloudflare/cloudflare-docs/pull/19890#issuecomment-2655205092 but am wondering if anyone here knows more?

Hello everyone. I am new to Cloudflare

Hello everyone. I am new to Cloudflare and my first experience failed. I've decided to create R2 bucket in Cloudflare and store my blog's images there. I have created the storage, changed Nameservers and Connected Domain. Now my website looks like this https://schulmatheapp.de. I don't know what to do, even after reading https://developers.cloudflare.com/r2/buckets/public-buckets. Please help me, thanks in advance.
