■ Affected services


■ Cause of the issue
PORTERS Connect API has become unstable.

The cause was a heavy load on the server due to massive accesses, resulting in significant processing delays and resulting errors. As a temporary measure, we added more servers to handle the large number of access requests.


■ Action

While continuing to increase the number of servers, we will prioritize server replacement, which was scheduled to be implemented this fiscal year, and distribute the load. We are also considering reviewing settings for mass access and setting a request limit.
