Dear Customers, We would like to inform you about the cause of the outage of a large part of the services that occurred on Tuesday, June 1, 2021. As we have stated earlier, the cause of the outage was a massive DDoS attack on the infrastructure of Dial Telecom, a.s.
Dial Telecom a.s., one of the leading Czech providers of data and voice services, recently averted a massive DDoS attack of over 65 Gbps, which affected one of the clients in the Czech Republic. The AntiDDoS protection applied by Dial Telecom is so strong that the attack was eventually averted without any disruption to other traffic.
Dial Telecom a.s., a leading Czech provider of data and voice services, has recently made extensive investments in the development of national and metropolitan optical networks and in connecting office buildings and business centres. The investment of almost one hundred million crowns has also affected the increase of existing capacities and network security. Despite the unfavourable economic situation due to Covid 19, Dial Telecom continues to think about its customers, innovate technologies and expand its services.
The launch of the 2nd wave of vaccination registrations for teachers and seniors 70+, in connection with the occupancy of line 1221, located in the Dial Telecom network, went smoothly as expected. The smooth running was influenced by several factors.
