Seems like clickbait...
Not necessarily saying any of those things (e.g., shutting off internet access) have or will occur - I'm pretty ignorant of the situation on the ground. I'm just saying that from a statistical perspective, I'm afraid it'd be a needle/haystack situation.
Maybe the number of DNS requests from distinct IP addresses goes down. As you say, traffic/data volume might keep more constant.

I've seen this pattern before (Epstein, Douma, the principle of net neutrality etc.). Fake data is released to muddy the water hoping that someone seeking for the truth is accidentally going to pick it up to then discredit / censor this person. If someone will then leak the actual truth that is similar to the faked one people are then less likely to look at it even if proof is provided.
