Although UIM is not directly impacted by this, we have seen a few impacts/side effects related to the crash/reboot cycle of Windows systems, particularly on the DX UIM Primary Hub server.
We have published a KB which outlines the potential impacts (mostly related to corrupted .cfg files) and resolutions - this will be updated continuously as we encounter more scenarios.
If you have recovered from the Crowstrike incident only to find that you are experiencing a DX UIM outage please check the following:
