Scheduled upgrade on ~okeanos service

Hello ~okeanos users,

We'd like to inform you about scheduled upgrade on ~okeanos service between 10:00 EET and 12:00 EET on Monday, January 22.

Your VMs and Pithos+ files should remain unaffected. The upgrade is expected to cause minor disruptions to the ~okeanos service. Astakos, Cyclades and Pithos+ Web UIs and their APIs will be unavailable for a short time during the upgrade.

No loss of connectivity is expected for the VMs.

Thanks for your understanding,
the ~okeanos team

SECURITY UPDATE: Spectre and Meltdown vulnerabilities

Hi ~okeanos users,

Early this month, security researchers reported two critical vulnerabilities: Spectre and Meltdown. These vulnerabilities allow attackers to access sensitive information (such as passwords), due to a design flaw, which affects Intel, ARM and some AMD processors. Specifically, Meltdown allows a process to bypass the mechanisms that isolate it from accessing the memory address space of other processes and the operating system. Respectively, with Spectre a process can access arbitrary memory locations of other related processes.

In order to protect the virtual machines, the physical nodes of ~okeanos have been patched with all the currently available security updates, with no service interruption. Furthermore, to better protect your virtual machines, we urge you to perform all the available security and kernel updates, as well as security updates on various applications such as web browsers, as soon as possible.

For a more thorough explanation on this subject, we suggest you read the following :

    Security Update: WannaCry ransomware

    Hi ~okeanos 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.

    For a more thorough explanation on this subject, we suggest you read the following blog posts:
