SysEleven Stack SysEleven Stack maintenance end

We're happy to notify you that the maintenance has successfully concluded.

Now that the maintenance has been completed the following issues should be resolved:

  • The temporary loss of connectivity of virtual machines
  • The temporary loss of internet connectivity
  • Problems with MTU-size under specific circumstances

We'd like to thank you for your patience.

SysEleven Stack SyselEven Stack maintainance update

Update: The scheduled network update runs as expected. We finished updating our outbound traffic components and also our compute nodes. The last component will be our controller infrastructure before we have finished the whole update of the SysEleven Stack.

SysEleven Stack SysEleven Stack maintenance start

As previously announced, we're starting the maintenance on the SysEleven Stack now. Assuming everything goes according to plan, we should be done by 12:00 CET (11:00 UTC).

During the maintenance, the following degradations in service will occur:

  • The SysEleven Stack API and webinterface will be unavailable.
  • The network connectivity of the virtual machines will have multiple interruptions of up to 90 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.

We apologize for any inconvenience this might cause and we will notify you once the maintenance has completed.
