Let's see if we can translate this pseuo-technical business speak into something everyone can understand:

... unusual traffic management and capacity optimisation techniques ...

They're going to introduce throttling.

...those who need them most...

But not for business users.

...much of the detail on this is either redacted or in non-public documentation.

The public will be unhappy with how big of cluster flock this is, so it has to be kept secret.

...some workloads prioritised over others.

Lots of throttling. If you thought everything was slow before they do this...

...temporarily ...

Less than 100 years.

...some areas...

The bits with people in them.
