Update - Further attacks of 1-2 Tbit/s have hit our network today, our rules have filtered them out completely, so the network is not currently affected by an acute problem or performance problems. As the filters on our carrier aggregation switches are not yet working properly, we are leaving the incident open.

Monitoring - We monitor the situation after we have set appropriate filters. These filters have already been set due to one of the last incidents, we have to check why they did not work as expected, according to the current state of knowledge we have to assume that it is a software bug from Juniper. As already mentioned, we have sufficient bandwidth to our various carriers to filter even large DDoS attacks with well over 2 TBit/s without any problems.

Update - We are continuing to work on a fix for this issue.

Identified - Initial countermeasures were taken as part of the filtering process so that the latest attacks no longer had any impact. We are still working on a permanent solution.
