Update 3 (2020-09-21 10:35AM PST): Testing this morning is showing much, much better behavior than what we were seeing last week. Please let us know if you are still seeing unreasonable rate limiting.
Update 2 (2020-09-17 5:50PM PST): I am noticing improved behavior, but still seeing more rate limit exceptions than expected. We just released a new desktop version that improves rate-limited behavior for Amazon Drive/Photos, which should help to smooth things a bit while we wait for full recovery:
Update: We’ve been in touch with the Amazon folks and they were able to identify where the problem is. They’ve made some adjustments and I am starting to see some recovery. Things should hopefully get back to normal within a few hours and you should already see some improvement now.
We will continue to monitor closely.
We’ve started seeing elevated rate limiting from Amazon Drive/Photos in recent days. We have reached out to Amazon to see what is going on and we will report here once we hear back from them.
In the meantime we are looking at ways we can better handle their rate limiting errors to provide a smoother experience (as much as is possible).
If you are currently unable to retrieve the data that you need immediately you should still be able to access your data from the Amazon web client, here: https://www.amazon.com/clouddrive . Their web client does not seem to be affected by the same Amazon errors we are seeing returned via their API.
Apologies for the inconvenience.
