> No one suggested it isn’t censorship,
In fact, some replies suggested it’s more commercial actions. We said it's
"likely influenced by commercial decisions", we didn't say censorship is
out of the question. We still think censorship is the possible cause, but
we run out of methods to verify it, that's why we switched to commercial
actions to try our luck. If commercial actions don't seem to cause the
slowdown, then it would be definitely censorship.

Most of the performance hit is because of commercial actions, not

Once again we are confused by the accusation.  We don't want to bait anyone
for anything.

Not deploying enough international capacity is absolutely a form or
> censorship deployed to great avail
 Yes we agree it is also a form of censorship. However, it is based on the
assumption that China didn't deploy enough international capacity, which we
don't have direct proof of it. On the contrary, from the stable performance
of the traffic going out of China, it is very likely the assumption is not
true. They might have enough physical capacity, but they don't make good
use of it.
