Currently we are facing issues with the SysEleven Stack Load Balancer (Octavia LBaaS) API. We are working on a solution and keep you informed.
The outage only affects creating or deleting load balancers, or changing existing load balancers.
Neutron LBaaS is not affected.
UPDATE 9:30: The API is now working again, but we expect that this problem can reoccur. We identified a performance issue and are working in the background to resolve it.
We apologise for any inconveniences.
