The Swisscom Dynamic Computing Services Team would like to share with you some important information about compatibility issues which can occur on Virtual Machine (VM) level. Since our last upgrade of the VMware components to version 5.5 (Build 2143827), Swisscom partners have reported compatibility issues with a widely used Citrix software component. The newly installed VMware version has caused outages of the Citrix NetScaler (see further information here). We recommend that you make sure to check compatibility with Citrix if you are using this solution yourself.
To our knowledge, this is currently the only known widely used software showing compatibility issues with the installed VMware version (Build 2143827). In order to ensure that you will not experience any inconvenience, we kindly ask you to verify whether any software you have installed or would like to use in the future is compatible with our infrastructure.
