iThena.Computational: The project comes back to life
After a long break in the operation of iThena.Computational 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 12:34:12 to 2026-01-17 15:47:33, i.e., 1563 hours and 13 minutes.
No data should be lost.
Thank you all very much for your patience...
