Error 503 "Too Many Requests"

[Richard]

My users are going through another spell of getting error 503 (Too Many Requests) on requests to the GCP server. These happen most often with users who use GCP heavily and are submitting a lot of print jobs. This can be disruptive for users who are running businesses or schools on GCP using my proxy. It would be very helpful to know what the criteria is for the error 503. What constitutes too many requests? With this information I can work on my proxy and with my users to mitigate the problem, which would be good for them and good for GCP.

I don't understand why the GCP team has not responded to this post. My users still run into this error and I can't think of a reason why information about the error can't be shared so I can improve the situation for my users and reducing the traffic that causes the 503 would be good for GCP.

We never provided guidelines on quotas, and we don't know how's your service configuration, and which APIs are failing.

A typical case for this problem is when a single robot account ends up managing a large amount of print jobs (thousands of them) in a short time period. To avoid that it is important that not too many printers are registered under the same robot account.

I hope that it helps.

It would help to know what you mean by "managing", "short period of time" and "too many printers". That said, it appears the 503 problem happens with any of the GCP interfaces. I see it on submit, fetch and control. In most cases the user has only a few printers and may only process a few jobs per day. There are users with large numbers of printers but by an large I don't see the 503 with them. I see it on users that appears to be a single person or very small business and there is no indication (though my data collection does not allow me to be 100% sure) the users have more than a few printers and process more than a  few jobs a day. There may be some condition I can't see that causes more traffic than I think is happening but the idea that these users processing large volumes just does not seem to hold up.
