The iThena distributed project concerns experimental mapping of network structures included in the Internet. The project is in closed beta phase. Currently, the only application available in the project (iThena CNode) performs a sequence of traceroute procedures from client computers. The resulting data is sent back to the server and submitted to the main database, where it can be further analyzed.

Currently the main supported and recommended platform is x86_64-pc-linux-gnu, windows_intelx86 and windows_x86_64. After joining the project, accept the download of test/beta applications in the settings (all currently applications is in a Beta stage). This can be changed by checking the appropriate box 'Run test applications?' in 'iThena preferences' in your profile after logging in.

Network structure mapping summaries will be available online.

Two applications are currently active: iThena CNode and iThena PERF.
The iThena CNode application tests delays, possible losses and routing of network packets.
The iThena PERF application mainly tests bandwidth to defined endpoints.

Open-Source Proxmox platform as part of the infrastructure

As part of our own initiatives we use open-source software.

Such systems based on open-source model are BOINC, and Elastic Stack.

We use advanced virtualization technologies and LXC containers based on Proxmox Virtual Environment.

Following the information on Wikipedia:

Proxmox Virtual Environment is an open-source server virtualization management platform. It is a Debian-based Linux distribution with a modified Ubuntu LTS kernel and allows deployment and management of virtual machines and containers. Proxmox VE includes a web console and command-line tools, and provides a REST API for third-party tools.

Open-source models built by communities in a huge way are very interesting.

We encourage you to support open-source initiatives and take advantage of such environments!

First summary of a major SBG Strasbourg incident
On March 10, 2021, a major fire occurred in the datacenter area of Strasbourg (OVH).

In the incident, one component of the iThena project was completely destroyed.

Another component located in SBG3 was temporarily shut down (only power sections destroyed). According to OVH, the SBG3 infrastructure we use should be up and running around March 22, 2021.

There may be issues with the iThena project applications.
These issues will completely disappear when the SBG3 zone is fully restored by OVH engineers.

At the same time, our team has developed improvements in the application code to fix such problems in the future.

You are welcome to test the new version of iThena CNODE application (v1.18b1).
