2021/06/01 Wireless LAN communication failure on Omiya Campus on May 27

On May 27th, there was a communication failure on the Omiya Campus Wireless LAN from around 11:00 to 11:25. As a result, all users and services using the wireless LAN were unable to use it.

We have not yet identified the complete cause of this problem, but we believe that one of the causes is that some networks experienced loops and network instability before the time of the failure.
We have already identified and implemented countermeasures for the looped areas.

We apologize for any inconvenience this may have caused.
