* BGP4 IPv4 reworking already in progress since 06/2016
* BGP4 IPv6 reworking already in progress since 07/2016

* reworking of backbone internal iBGP for IPv4 and IPv6 finished
* cleanup and validating in progress

* We have bugfixed one IPv6 transit connection today
* We have deployed two new IP-transit connections for IPv6 today.

Outage testing:
We are testing an outage of the whole fiber connection between Jena -> Amsterdam since 0700h CEST. We will finish the test around 1200h CEST.

Outage testing successful finished, no impact for monitoring and customers detected.

Outage testing:
We are testing an outage of the whole fiber connection between Jena -> Frankfurt since 0700h CEST. We will finish the test around 1200h CEST.

Impact for all customers:
+ ~20ms latency to Frankfurt

Outage testing successful finished. No outage detected. Network and Monitoring behavior works as expected.

Outage testing:
We are testing an outage of the whole fiber connection between Frankfurt -> Amsterdam since 1100h CEST. We will finish the test around 1200h CEST.

Impact for all customers:
* routing loops may occur, please reports them via customer panel to our support.

Outage testing successful finished. No outage or other bug detected. Network and Monitoring behavior works as expected.

We are going finalize a change of the backbone connection between Fra - Ams with an outage test of the connection Jena -> Fra.

Time-window: 20.11.2016, 5-9h
Impact for customers:
* routing change Jena -> Ams -> Fra
* higher latency to Fra
* packet loss is not expected but may occur
* no further impact expected

The test has been finished. The test was successful.

Additional work to do:
We have measured a bandwidth throughput issue during the test. We now going to find out the reason of this issue and work on it.

we are reworking the BGP4 config to peerings and upstreams.

impact for customers:
* routing changes occur
* flapping routed my occur
* latency changes my occur
