Anyone who sees 100G as the standard today can easily forget what that step meant back then. It was a true technological leap, both in terms of hardware and financially. Suddenly, scaling was no longer thought of in small increments; instead, capacity could be planned on an entirely new level.

Another important technological milestone was the leasing of our own dark fiber, but above all the operation of our own DWDM systems on the routes. Only then did true scalability, maximum control, and independent network expansion become possible. Ulrich, Head of Network and IT Operations, looks back on the year
