    SECURITY UPDATE: WANNACRY RANSOMWARE

    Hi ~okeanos-global users,

    There is a rather dangerous ransomware, the WannaCry / Wcry / WannaCrypt ransomware, that has been spreading since Friday, May 12. The ransomware takes advantage of the MS17-010 vulnerability that affects Microsoft Operating Systems.

    In order to protect the virtual machines from exposure to the WannaCry / Wcry / WannaCrypt ransomware, all incoming TCP traffic to ports 137-139 & 445 has been blocked.

    The aforementioned firewall rules were applied to partially prevent the ransomware from spreading. Therefore, we urge you to perform all the necessary updates on your Windows virtual machines.

    SURVIVING A RADOS OUTAGE

    Hi ~okeanos-global users,

    Recently ~okeanos-global service faced some disruptions, as we informed you on a previous blog post. Let's shed some light on what caused them.

    The ~okeanos-global storage backend (Archipelago) is backed by Ceph, an open-source distributed software-defined storage solution. On Friday, September 9, at 9 p.m., Object Storage Daemons (OSDs) of the RADOS cluster became unstable resulting in the cluster erroneously marking OSDs as down. This incident led to I/O freeze and cluster malfunctioning. In order to ensure data integrity, we had to resort to special handling and tooling and managed ... read more
