Otkritie bank's fiber optic cable was accidentally cut during construction work on Smolenskaya Square in Moscow. The incident resulted in technical problems for millions of bank customers. Along with this, there were failures in the operation of ATMs. The banking application "Rocketbank" also temporarily stopped working.

The situation became so complicated due to the fact that the cable violation was discovered after 18.00, when the builders had already finished their working day. Together with the Otkritie bank, the Tochka bank also suffered. Now the damage is localized, and the problem with the cable is almost eliminated. The work of ATMs and other infrastructure of the bank has already been restored.
