Dear Customer,



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.

95.211.48.0/21

95.211.56.0/23

62.212.88.0/23

[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.
