On 10. 1. 2013 from 00:00-02:00 we will preventively test the redundant involvement of our new frontier routers. We perform the Test by actually disconnecting the primary router to see if the traffic is properly redirected to the secondary router after further optimizations. The tests are related to the exchange of our edge network elements, upgrade our data center connection to 10 Gbps and increase the throughput of our internal backbone network to 2×10 Gbps. Everything is done in order to prepare our network infrastructure to grow data traffic in the future and increase its resilience to DoS attacks. This service window can be used to predict very short downtime of availability of our services, but they should not exceed 10 minutes in total. If unforeseen events occur, please refer to this location for more information. Thank you for your understanding.
