Scheduled Maintenance
Software Upgrade -

We need to reboot the cloud hypervisor in order to upgrade the running software to a recent version. Cloud Servers will be shut down by ACPI before the maintenance starts. After the reboot of the physical server has been carried out, we will start all Cloud Servers. Please make sure that your Cloud Server responds to ACPI commands.
Affected customers has been informed by email.

Hardware Upgrade - Internal Hypervisor

On 18th October 2019 at 08:00 pm till 10:00 pm (German time), we will carry out maintenance work on some internal servers / services.

The following services will be offline during the maintenance work:,,,,,, (our phone number)

The following services are backed by redundancy:,

Some of the services are not customer facing. No impact on customer infrastructure is expected.

Hardware Upgrade - Core Router -

We are going to replace the current routing stack with a more powerful stack consisting of two Juniper QFX5100-48S. The upgrade will be carried out at the 18th October 2019, starting at 11:30 pm. Our upgrade plan consists of the following steps:

  1. We will turn the new gear in operation and create a port-channel with all v-lans between both old and new stack
  2. Once the port-channel is active, we will re-plug all uplink ports from the old to the new core causing a maximum downtime of ~5-10 minutes per customer
  3. After replugging all the ports to the new gear, we will switch the routing (BGP Sessions) from the old to the new core - this will cause a downtime of additional 5-10 minutes per customer
  4. We will carry out last checks if the new gear behaves well, if something goes wrong we can still switch back to routing over the old core

We do expect a total downtime of 30 minutes per customer if everything works as planned. However, we do announce a maintenance timeframe from 11:30 pm till 19.10.2019 01:00 am. Please expect, that in the worst case the maintenance may take longer as 30 minutes. Due to our experience with such upgrades, we are confident that the maintenance will not take longer than 30 minutes.

Affected customers will be informed by email at least 14 days before the planned work happens. In case you are unsure, if your service is affected, please open a ticket with our customer service.
