On April 9, 2024, Inkling restarted the central API services after adding additional capacity. Following the restart, the services that process central queue items failed to connect to the queue properly. This caused items in the queue to have their processing delayed. This was mostly seen in a delay publishing Inkdocs.
To resolve the issue, Inkling engineers reconnected the services to the queue. By 10:30 AM PT on April 10, 2024, the services processed the backlog and resumed normal service. No data was lost in this process, only delayed. Changes to the queueing system were made to ensure this does not reoccur.
