Region/datacenter: OpenStack region KNA1 (Karlskrona, Sweden)

Maintenance window starts: 2021-04-26 08.00 CEST
Maintenance window ends: 2021-04-30 17.00 CEST

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 Train to Victoria, which will offer certain new functions but also address a list of known bugs. Some functions will improve seen to maturity level.
There will, in parallel, be work security wise to further increase protection and to address vulnerabilities. Furthermore there will be improvements to operations automation and those improvement will allow a high flexibility for us to operate the cloud more seamless, pinpointing time frames that could potentially involve a slightly higher risk of minor disruption.
Please note that there may be a shorter time frame, still to be defined, involving a brief disruption of running services Our ambition is to carry out the majority of the maintenance window with little to no impact on running services, All infrastructure services will be restarted in a controlled and timely manner, in order for proper security patching.

Expected customer impact:
- This maintenance will minimize the impact on customers virtual machines and cloud resources reachability while upgrading the network nodes, controlled router failover will be done where you may experience outage ranging from a few seconds.
- During maintenance you may experience API issues or unavailability during new resource creation or editing already created ones. It is recommended to postpone operations with OpenStack API when possible to the time after maintenance.
