On Tuesday, 29 July 2025, at 10:48 (24-hour format), an issue occurred preventing SSH connections to the General Analysis Division Gateway Node (gw.ddbj.nig.ac.jp).

The issue occurred due to a memory shortage on the gateway node caused by the execution of a user program. This caused the sssd process to stop, making SSH connections to the gateway node unavailable.

To address the issue, the sssd service was restarted at 12:19 on the same day, and the service has since been fully restored.

If you are unable to log in to gw.ddbj.nig.ac.jp, try logging in via the alternative gateway node, gw2.ddbj.nig.ac.jp. The login process is the same for both nodes.

For more information on login procedures, refer to the “How to Login to the Gateway node (The general analysis division)”.
