Dear Valued Customer,

City Network would like to inform you that we have planned maintenance as scheduled below. This post is an update to previously communicated information.

Customer Intervention WILL BE required.

Region/datacenter: Openstack region STO2 (Stockholm, Sweden)
Maintenance window starts: 2020-02-03 08.00 CET
Maintenance window ends: 2020-02-07 17.00 CET

Maintenance scope:
Throughout the maintenance window, a number of improvements will be implemented – from functionality to security alignment.

The major part of the scope is an Openstack upgrade from Rocky to Train, which will offer certain new functions but also address a list of known bugs.
Some functions will improve seen to maturity level and Magnum (Container Orchestation) in particular.
Our ambition is to carry out the majority of the maintenance window with little to no impact on running services.

Expected customer impact:
No customer impact is expected other than very brief moment of packet loss, when and if active customer services are live migrated between nodes (compute and network)

Furthermore, Load Balancer as a Service v2 will be deprecated and removed in the Openstack Train release – why conversion of all existing LBaaSv2 services will be carried out througout the maintenance. Affected customers will be contacted individually with additional information.
