Thank you!

Dear CivilEA friends,

I sincerely apologize for my long absence from the forum.

For many months, my country, Iran, has been living through dark and painful days. A devastating war imposed by the United States and Israel brought fear, destruction, and suffering to millions of ordinary people. Under the banners of “freedom” and “fighting terrorism,” innocent civilians were killed, including children whose only crime was being born in the wrong place at the wrong time. Families lost their homes, parents buried their children, and entire communities were left traumatized.

As an engineer, it was heartbreaking for me to witness the destruction of infrastructures that represented years of human effort, science, and engineering achievement. Beautiful bridges, industrial facilities, steel plants, and petrochemical complexes built by Iranian engineers were damaged or destroyed. Seeing creations built for development and life become targets of war is a pain difficult to describe.

At the same time, Iran experienced one of the harshest internet shutdowns in modern history. According to international monitoring organizations such as NetBlocks, access to the global internet was almost completely cut off starting February 28. For long periods, we were isolated from the world. Only through expensive and unstable connections was I sometimes able to briefly access the international internet.

The economic consequences have also been severe. Inflation has become overwhelming, and the prices of many essential goods have increased two, three, or even six times. Daily life has become extremely difficult for ordinary people.

What hurts even more is hearing all of this destruction described as a mission for peace, humanity, or civilization. Iran is one of the oldest continuous civilizations on Earth, with thousands of years of history, culture, science, literature, and engineering heritage — far older than the relatively young histories of modern political powers that now lecture the world about civilization.

History has seen many wars, empires, and aggressors rise and disappear. Yet Iran has endured through centuries, and it will endure again.

Thank you for your understanding, your patience, and your kindness during my long absence.

I am still here, and I remain honored to be part of this community.

With respect,
Mohsen

We sincerely apologize to all our users for the recent service disruption.
For nearly three weeks, access to international internet services in Iran was completely cut off due to nationwide protests, and unfortunately, there was no possible way to establish a stable connection during this period. As a result, we were unable to provide timely updates, support, or normal service operations.
We truly appreciate your patience, understanding, and continued trust, and we are committed to serving you better moving forward.
Thank you for being with us.
