[20120914]Emergency maintenance; reload router German Legacy network [Update]

Startdate: September 14th 2012 06:00:00 (CEST)
Enddate: September 14th 2012 08:00:00 (CEST)

Dear customer,

As we are experiencing some issues with one of the core routers for the German Legacy network (Netdirekt) we have planned an emergency reload.

During this maintenance there is no expected downtime, however customers might experience higher latency and short periods of packet loss when routes are being relearned.

We do apologize for any inconvenience caused, and do our best to reduce the impact.

Affected IP ranges are:
37.1.216.0/21
37.58.48.0/20
46.166.151.0/24
46.166.152.0/21
77.223.144.0/23
78.159.96.0/19
84.16.224.0/19
89.149.192.0/18
91.109.16.0/20
91.191.160.0/21
95.168.160.0/19
178.162.128.0/17
188.72.192.0/18
212.95.32.0/19
217.20.112.0/21
217.20.120.0/22
217.20.126.0/23
217.73.56.0/21

Update at 06:45
After the maintenance the initial issue is resolved. Due to relearning BGP routes the CPU of one router increased to much causing BGP to drop sessions. Please read more on: http://www.leasewebnoc.com/en/networkstatus/leaseweb-germany-wuppertal-router-down-1
