China is beefing up filtering measures

Dear Nanogers,

By now, I'm pretty that the community has heard that china is planning to
increase (once again) filtering measures by limiting ports 80 / 443 / 8080 :

I've been doing some googling (read above) and I have come to the following
conclusions :

- Only clear thing is that a "commercial" ISP can register with CN gov to
lift that filtering ?

- This should be enforced by Feb, 1st.

- Pretty much all the rest is unclear when it comes to the : who ? what ?
how ?

I'm trying to understand exactly what we might be dealing with here.

Do anyone happen to have a clear view on this ? Are some of you already
affected by this ?

Thank you for your feedbacks.

Best regards.

Evil.
