D"Class A" operations aren't a higher/faster tier you are trying to get into. Class A (generally) are write operations, class B are (generally) read operations.
Aahhh i see
Athanks
DYa, depends on your application. If you need to make sure you aren't overwriting something inadvertently, it would make sense to do a HEAD before a PUT.
Kdepending on what you're looking for in the
HEAD
Bit's deterministic and overwriting isn't the end of the world but avoiding class A is the goal there
Bi actually keep a cached list of bucket contents and remove entries when they are deleted, so that i can avoid having to do a head or list_objects etc, for the most part. but i still have it there for the more expensive write operations, as they are operating in parallel
Bthere's more than 800,000 objects in these buckets
ᓚhi there! anyone knows where can I report an abuse commited in r2? Cloudflare team is not paying attention to my claims.
ᓚthanks in advance 
U?abuse
FIf you feel that a site is engaging in illegal or inappropriate activities, you can submit an abuse report at https://abuse.cloudflare.com/. The Trust and Safety team will then review the details and reply if appropriate. You can also report the site to your relevant local authorities. Reports cannot be filed via Discord or individual employees.
ᓚa phishing attack, i already reported through abuse.cloudflare.com with no success
UAs the abuse message says there is nothing we can do via discord. It has to be through the abuse form.
ᓚnoted, thanks
Pis there support for programatically creating API keys that are scoped to a specific prefix in a bucket? the use case is for allowing an untrusted user to upload a large file to a specific prefix. it seems that to use presigned URLs + multipart uploads, our API would have to create a URL for each part being uploaded which seems a bit messy
UI’m not sure if you need to create many urls for the multipart upload or not but if that is the case it’s just a client side operation so creating up to 10k parts which is the max should easily be doable in the initiate imo 
YWhy can't I submit data in the browser when I pre sign the URL? Continuously prompting for cross domain issues, how to solve them, or does R2 not support cross domain put?
KYou need to setup a CORS policy, same as S3.
Y
YIsn't that right?

YI see, I am using CF to parse my s3 port. I want to implement my own domain name instead of the s3 interface, but how can I resolve the error that occurred?
HHey guys, i was wondering how to connect to this csm? I want to activate R2 in my account, but then this pops up.
EIf you can't work it out then write in to support and we can find out for you
Hthat's weird, i'm the one who made the account, recently, no subscriptions too.
Hyeah, i've sent support ticket regarding this issue
EThanks, we'll follow up there
BTo enable R2 contact your Customer Success Manager
EAre you getting this error as well?
B
BHow to enable R2 ? please
EI'm escalating this to the R2 team now
BYou are the best!
E@Bruce Lee can you try again now? It should be fixed
BIt worked. Thank you so much!
�I have a question about class B operations, let's say I host a 100MB video file with a custom domain and a yellow cloud in dns and the user skips around the video, so the browser makes requests like in the picture, how many class B operations have been done?
�additional info: 1st request was was
Cf-Cache-Status: MISSHIT
IThis isn't related to R2 - you might want to ask in #general-discussions
Soops my bad, thought i was
�update the root cerficates on your server / curl

AHello Bruce, I got it working after refreshing page for 4-5 times. I don't know really why it worked but it worked for me. After refreshing multiple time I was redirected to billing page to enable R2.
SDo you have a custom video playback setup? Generally browsers will download the entire video once, and then skipping around doesn’t make any more requests.
In your case though, yes, every request that isn’t a cache hit would count as a Class B operation if I’m understanding things correctly
