CloudKit seems to have a little trouble the last 12 hours (dashboard seems to be broken, uploading takes forever or causes a 503 server error).
Also, we encountered a very strange error when uploading CKRecords assigned to a signle parent: If more than 200 childs are present, it fails with the error "Invalid Arguments - Parent reference max collection limit exceeded". This only seems to happen in newly created zones with newly created parent records.
Anyone else encountering this? I never saw this error before. Having hundrets of children assigned to a parent record was no issue a few days ago.
Problem with "Parent reference max collection limit exceeded" is solved - occassional 503s and timeouts are still present.
The occassional HTTP 503 errors and timeouts are gone as of today! Yay!
