CloudSigma would like to inform you that we will be performing upgrades to the switching fabric in ZRH including both hardware and software upgrades. The upgrades will improve network stability and will lower network latency within the cloud. We have deployed this configuration successfully in other locations for up to one year already.
Based on internal testing the lowest risk with minimal impact methodology has been found to be as follows:
(1) Prepare the switches for upgrade
(2) Move IP addresses
(3) Move configurations
This will will minimize network interruptions, which is expected to be a maximum of two minutes per switch.
All support activities will be conducted under the direct supervision of CloudSigma’s operations staff.
During the maintenance some VMs might experience brief packet loss but it is anticipated that it will improve network within the cloud. This general upgrade to the networking fabric will enable non-service affecting upgrades in the future with regards to the cloud network.
Please accept our sincere apologies for the caused inconveniences.
Thank you for your understanding.
While it is important for CloudSigma to perform maintenance such as this to ensure the quality of our services, we try to do everything possible to minimize any inconvenience to our customers. We appreciate your patience and welcome any feedback.
