Centralized infrastructure is fragile and to the extent that the internet has become centralized unscheduled Internet shutdowns are bound to happen. The benefit of scheduled Internet shutdown is that people can prepare for it while at the same time gaining experience which helps with dealing with an unscheduled Internet shutdown.
On the other hand, if we force all systems to be resilient to an internet shutdown then we'd end up regressing society by a lot. Think about how much more work a single doctor is able to handle more efficiently by having internet access (eg. charts, patient history, access to all the world's libraries) that would be lost without the internet.
That's because the unannounced firedrills don't involve setting the building on fire. A "drill" equivalent would be if we all pretended the internet is down sometimes, and in some cases that still might be impossible to do without negative consequences.

If we don't force critical systems to be resilient to an internet shutdown, we'll be doing the meme. Specifically:
Weinberg’s 2nd Law:
If builders built buildings the way programmers wrote programs, then the first woodpecker that came along would destroy civilization.
we do annual unannounced firedrills and now one dies as a consequence.

Fire drills do involve denying access, though. We wouldn't need to bomb the datacenters but we would need to make them inaccessible.
