We will perform a software upgrade on two of the standby routers in the Evoswitch datacenter. Since we use HSRP to provide redundancy there should be no impact because of this. If you have a private rack please make sure that redundancy is working correctly.

The following ranges are impacted for the first router:
95.211.48.0/21
95.211.56.0/23
62.212.88.0/23
85.17.68.0/22
85.17.135.0/24
85.17.181.0/24
178.18.21.0/23
178.18.22.0/24
193.27.73.252
193.27.72.0/23

The following for the second router:
91.215.156.0/24
31.186.168.0/23
62.212.67.0/24
62.212.74.0/24
62.212.91.0/24
82.192.86.0/24
82.192.71.0/24
85.17.134.0/24

[UPDATE @ 06:15]
The upgrade of both routers is done and was a success. For both routers the interface status and standby status for HSRP have been verified. These were the same as before and OK.
