ftp.tsukuba.wide.ad.jp has been unavailable since approximately 9:00 JST on September 7, 2026.
We expected a brief service interruption during a scheduled power shutdown for a routine electrical insulation inspection. However, an operational error during the shutdown left us unable to restore the service after power returned, and the outage is ongoing.
Update: September 8, 2026
Data was lost due to the operational error, and we have not yet been able to fully restore the service.
We ask for your patience until the service is fully restored.
