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.

iThena.Measurements: The project comes back to life
After a long break in the operation of iThena.Measurements Project, the system came back to life.
The problems were related to major technical issues.
Initially, there were problems with the fiber optic connection.
Later, after the fiber optic cable was repaired, problems with the main server arose. Unfortunately, the problem turned out to be quite complex and the entire motherboard in the rack server had to be replaced.
There was no official information. Several people wrote to me by email and I replied with a brief message saying that I hoped everything could be repaired without any loss of data. Fortunately, it worked...
It was the longest interruption in the system's operation in history and lasted from 2025-11-13 12:35:47 to 2026-01-17 15:47:30, i.e., 1563 hours and 11 minutes.
No data should be lost.
Thank you all very much for your patience...
