I'm using AWS to run some data processing. I have 400 spot instances in EC2 with 4 processes each, all of them writing to a single bucket in S3. I've started to get a (apparently uncommon) error saying:

503: Slow Down

Does anyone know what the actual request limit is for an S3 bucket? I cannot find any AWS documentation on it.

Thank you!
