On Tuesday, May 18, 2021, we created a maintenance window starting from 23:00 CET till 01:00 hours next day to make the public connectivity of OpenStack 2.0 even more resilient.
This maintenance window is an extension of the initial maintenance window which was scheduled on Tuesday, April 13, 2021.
During the initial maintenance window we could not execute all nessesary tasks, which required us to plan a new maintenance window to complete all remaining maintenance required.
With this message we would like to inform you about the consequences for you.
This writing includes the following items:
1. What is changing?
2. What does this mean for you?
3. More information
1. What is changing?
We've identified a scenario in which public connectivity is degraded and our existing redundancy does not fill this unexpected gap.
This scenario, in combination with better and enhanced connectivity (also for any future platforms), requires us to implement a policy change in our public routers. This policy change will enable a new routing entry which will make the public connectivity in the future more resilient and redundant.
We have already extensively tested and validated this change in our testing environment, ensuring us that this policy works as expected, making the platform even more redundant and resilient.
2. What does this mean for you?
In order to make this change as painless as possible, we will temporarily reduce redundancy, in order to apply this policy.
During the maintenance window, the public connectivity will be re-routed through other redundant routes. No impact is expected, though in exceptional cases downtime can be experienced up to several seconds.
When all policies have been applied, redundancy will be restored fully.
