Ah, the age-old battle of man versus machine. Or in this case, dPaolaloper versus Logstore. My money's on B) - those partitions can only handle so much before they start throwing 403s around.

True, but I still think B) is the main culprit here.

Could also be a network delay causing the issue.

Maybe we should check the partition limits to confirm.

I think you're right, B) seems like the most likely cause.

I don't know, guys. This question is making my head spin. Maybe the dPaolaloper should try writing their logs with a T-Rex instead of an API? Just a thought.

D) is an interesting choice, but I'm not convinced that's the issue here. Seems more likely it's a throughput or capacity problem.

I'm going to have to go with B) on this one. Exceeded write throughput sounds like the most plausible explanation for the 403 error.

C) is also a possible cause. If there's not enough space in the Logstore partition, the write operation could be rejected and return a 403 error.

B) seems like the most likely cause. If the write throughput of a single partition is limited, the 10 MB/s traffic could exceed that limit, resulting in the 403 error.
