]]>Between February 27th 2019 00:00 AM and 05:00 AM (UTC +1) we will perform planned maintenance in Region CBK
During this period the API in the CBK region is not available - leading to a loss of control.
During this period there will be:
Should you have any trouble following the maintenance work please contact us.
]]>The outage only affects spawning new virtual machines or changing existing resources.
We apologise for any inconveniences.
UPDATE 00:30:
We have identified the cause of the API issues in DBL and resolved the issues for most API operations.
Due to a bug in OpenStack API components, the DBL API services used CBK identity URLs for validating tokens, which did not work due to the planned maintenance.
We changed all internal identity URLs in the endpoint registry to region-agnostic URLs.
We are now working on fully resolving this issue for all API operations in DBL.
UPDATE 00:50: All issues are resolved.
]]>Should you have any trouble following the maintenance work please contact us.
]]>Should you have any trouble following the maintenance work please contact us.
]]>Should you have any trouble following the maintenance work please contact us.
]]>This is due to a mitigation we put in place that solves sporadic performance problems, when a virtual machine has been created or deleted. We are right now working on a better mitigation, that will not affect creating servers.
The issue only affects spawning new virtual machines with the L1.* flavor (Local SSD Storage).
We apologise for any inconveniences.
UPDATE 2019-02-13: The issues are fully resolved now. Creating and deleting Local SSD Storage instances will only take a few seconds now, and the time for creating and deleting VMs is constant, no matter what disk capacity.
]]>In order to offer the same features in both regions we will roll out new versions of our networking components in the CBK region.
The maintenance window is planned for 2019-02-13 from 00:00-05:00 (CET)
During the maintenance window we will update the networking components in the CBK region.
There will be the following service degradations within the maintenance window:
The DBL region will not be affected.
UPDATE 01:55: The maintenance has been completed.
Should you have any trouble following the maintenance work please contact us.
]]>Between January 23rd, 2018 00:00 AM and 06:00 AM (UTC +1) we will perform planned storage maintenance in Region DBL
During the maintenance window we will update the distributed storage software in our DBL region in order to fix a memory leak.
It is possible that IO requests are slow during the maintenance window.
Affected services:
Not affected:
UPDATE 04:32 AM (CET): The maintenance has been completed successfully.
Should you have any trouble following the maintenance work please contact us at cloudsupport@syseleven.de
]]>We created a oauth service with dex to authenticate our web applications against. Dex writes all of the session information into the etcd cluster. Due to a misconfigured monitoring we created over 500000 sessions in the etcd cluster. The database size grow from about 300MB to 700MB. That slowed down all cluster operations. During the whole incident customer applications were not affected, the MetaKube dashboard including cluster creation were regularly not working correctly when one of the master apiservers ran out of memory.
]]>Between January 17th, 2019 07:00 AM and 08:00 AM (UTC +1) we will perform planned maintenance in Region DBL
During the maintenance window we will update the SDN software in our DBL region in order to fix a memory leak.
During the maintenance window the following services will not be accessible:
The following services will not be affected:
Should you have any trouble following the maintenance work please contact us.
]]>Creating new VMs results in an error since 11:30 AM CET.
We are investigating.
We will keep you informed and apologise for any inconveniences.
UPDATE 11:53 CET: We have resolved the issue, and isolated the root cause.
]]>Network connectivity of VMs were not affected by this issue.
We apologise for any inconveniences.
]]>We will keep you informed and apologise for any inconveniences.
Update 11:23: The issue is fixed. Reason for outage: The SDN agent on one of our compute nodes crashed because of memory pressure. We are investigating the reason for the memory pressure.
]]>Our engineers are currently looking into them and will update this status page post with more information soon.
We apologise for any inconveniences.
UPDATE 14:30: We determined the impact. The errors are impacting a very small number of attempts to launch VMs. So far only one customer is affected. We are now looking for a solution.
UPDATE 15:30: The issue also affects Neutron API performance. If you are experience any troubles, please contact cloudsupport@syseleven.de
UPDATE 16:15: The API performance issues are now resolved.
UPDATE 17:00: The API issues are fully resolved now.
]]>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.
Update: 14:22
We identified a suspicious hardware node that slowed down the overall cluster performance. We are working to isolate that node and bring back cluster write performance.
Update: 14:23
We isolated the affected hardware and performance is back to normal. If you experience any problems please contact us.
We will keep you informed and apologise for any inconveniences.
UPDATE 4:14: Any network connectivity issues are solved now. Reason for outage was a faulty line card.
]]>Affected times for the region CBK
13:12 – 13:17 (MESZ)
14:32 – 14:37 (MESZ)
Affected times for the region DBL
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.
UPDATE 16:15:
We found out that a number of virtual machines lost their network connectivity due to the API issue. We are trying to bring them back online as soon as possible. Impacted customers have been informed by e-mail.
UPDATE 17:25:
We resolved the API issues and connectivity issues for virtual machines.
All customers that have been affected by connectivity issues should have been informed by e-mail.
Please contact us should you still have issues or need assistance.
