I have no data or information on the topic, but the use of English was fine for the apparent intended meaning:

"Almost 80% of communications go through a data center in X"

Does not mean that all traffic goes through a single data center in X. Just that it goes through one of potentially many data centers that happen to be in X.

You're right. It's fantastic to see how English comprehension is decaying, even in groups that supposedly are smarter than average. There's a fast decaying tendency in language comprehension overall, and I can only point to the fact that much of the new generation is unable and unwilling to read even a single book.
