  • [ID Server] Unstable node on one of servers for VPS customer - 14 Oct 2015

    October 14, 2015 by Benny K
  • Dear Customers,

    As of today, we noticed some strange issue that brought down one of the Indonesia node VPS at around 5PM. We noticed that during the incident, the load suddenly goes up till the server is not responsive. But since the node is running xen, there is nothing that could bring the load up as individual VPS are running at their own cpu core.

    We rebooted the server and all is back to normal, but we are uncertain on the cause. We have submitted server logs to the principal vendors for their investigations. Our suspect earlier could be due to the malfunction hdisk (elements grown in defect list is shown as non-zero) and will await their feedback if this could be the culprit.

    The issue only affects one of our indonesia server node. It does not affect existing reseller/shared hosting customers.

    If you are affected, you will receive a separate email in your inbox.


    We apologize for the inconvenience caused.

    Kind Regards,


    SOSYS.NET
