Hi,

We are requesting for this report(/reports/top-campaign-content/dimensions/item_breakdown) several times a day.
But , server returned 503 status code in a few accounts.
This problem starts since September 21st and it is remaining.
I tried it for a several time , but the result doesn't change.

Please tell me why it's happening and what we can do to solve this.

response headers:

503 backend read error

Error 503 backend read error
