We were facing issues with the SysEleven Stack Neutron API between Dec 29th 2018 and Jan 2nd 2019. Some Neutron API requests were slow, and a few requests might have timed out and failed. The reason was an almost-out-of-memory situation in the software of one of the three SDN controllers. The problem was fixed at 11:26 CET on Jan 2nd 2019.
Network connectivity of VMs were not affected by this issue.
We apologise for any inconveniences.
