Yes, it's apparently impacting all Windows machines running CrowdStrike. A fix has been deployed, but quite a mess nevertheless - airlines, banks, hospitals, TMT, and 911 call centers were all impacted. I had a client cancel a workshop this morning because of it.
We are just now recovering from it. Many applications have been impacted, including at least one significant app that’s still being fixed. It started about 9 hours ago now.
