On the 26th 9. 2012 from 00:00-02:00 We will test the redundant involvement of our new frontier routers. We perform the Test by actually disconnecting the primary router to see if the traffic to the secondary router is properly redirected. We verify that we have made the exchange of our boundary network elements correctly. The action is the last step of upgrading our data center connection from 1 to 10 Gbps and increasing the throughput of our internal backbone network to 2×10 Gbps. The goal is 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.
