]]>Update 11:05: The problem appears to be currently resolved but we are still investigating to understand the root cause.
Update 11:45: All Instances in our DBL region were affected by a loss of network.
The outage was caused by a maintenance command issued on one isolated and empty compute node that unexpectedly affected all hypervisors in the whole cluster. It raised the log level which led to our SDN agents to be overwhelmed by traffic.
We will conduct a post-mortem to find ways to prevent that error from happening again.
]]>We apologise for any inconveniences.
Update: 15:00 The problem was found and could be fixed immediately.
]]>Between November 20th, 2018 14:00 and 16:00 (UTC +1) we will perform planned maintenance in Region DBL
We plan to update components of the software-defined networking layer.
During the maintenance, the following degradations in service will occur:
The network connectivity of the virtual machines will have multiple interruptions of up to 45 seconds. This will affect all virtual machines on a compute node at the same time. We will try to avoid concurrent connectivity loss of multiple compute nodes.
access to the API/Dashboard will not be affected
SEOS (S3) will not be affected
storage availability will not be affected
Should you have any trouble following the maintenance work please contact us.
]]>We will keep you informed and apologise for any inconveniences.

12:05 – 12:15 (MESZ)
12:51 – 13:00 (MESZ)
13:50 – 14:00 (MESZ)
During these times it was possible that virtual machines did not respond due to IO wait. It might also have affected creating virtual machines and cinder volumes.
We will keep you informed and apologise for any inconveniences.
UPDATE 16:20
We identified that regular maintenance work on storage nodes (reboots) have indirectly caused this incident. The maintenance work is stopped until we find and resolve the root cause in close collaboration with the storage software vendor.
We will keep you informed on the results.
]]>We apologise for any inconveniences.
UPDATE 22:45
We have identified and resolved the networking API troubles.
We found a bad entry in the network state database of our SDN software, that caused a cascading failure: Internal locks could not be acquired anymore, which caused the API errors, which in turn caused networking troubles during live migrations in a small number of virtual machines.
We now understood the root cause and will post more information on actions we will take to prevent this from happening again once we conducted the post-mortem.
UPDATE 15. October
We are currently working the following action points:
Existing virtual machines are not affected.
Please contact us, should you have any troubles or need any assistance.
We apologise for any inconveniences.
