Why updating/patching Operating systems?
Patching is the process of repairing system vulnerabilities that are discovered after the infrastructure components have been released on the market. Patching is necessary to keep servers secure from attackers and viruses as well as free from bugs, which can weaken productivity.
OutSystems performs regular patching on all Public Cloud infrastructures' servers. Please note that these patching operations do not affect the OutSystems platform.
When will this maintenance occur?
OutSystems will notify PaaS customers of scheduled maintenance operations by email. To receive such notifications, you should be registered as an infrastructure contact. These emails will include the list of affected environments and the planned maintenance schedule (UTC 24 hour format).
In the .NET stack, OutSystems will install all Microsoft's critical, Important and Moderate updates to the Windows Operating System as well as relevant updates to the remaining software.
