15s delays when writing to R2 from Workers

Thank you! Yes, it seems like both that user's message and the incident are referring to the same problem. Not a good look of CF that it took them ~2-3 hours to acknowledge it. Even at the time of my message, we had already been seeing intermittent issues for some time.
