[ID server] Issue at xen-id5 server - 14 Aug - 11AM SGT

  • August 14, 2023 by Tech #1

Dear client,

We received down notification on 14 August around 11AM SGT on xen-id5.sosys.net and it was due to memory module not detected by the server. As such, we will be performing memory reseat and hard reboot to see if the issue is resolved. 

This urgent maintenance is scheduled to be on 15 Aug at around 12AM SGT for about 30 mins.

We apologize for the inconvenience

Thank you
