No. I imagine they are less sensitive and generally stay online and are only de-energized if the utility has an outage

But they can have their own internal fault and have to shutdown.
A single ~50MW facility dropping off the grid suddenly is something the grid can absorb fine.
The problem is with facility-level grid-responsive safety mechanisms. If the grid sags a bit and several DCs ~simultaneously disconnect, you have a problem. If the DCs going offline causes further instability that causes other facilities to disconnect or grid protection breakers to open, you have a cascading chain reaction
