Interesting that (according to Renesys) BT reconnected about 500 networks in Pakistan after the big fibre cut. I wonder if there's any data around that would tell us who filters and who doesn't?

having built an ISP or two in pakistan, PTCL (Pakistan Telecom) is not the
sole provider of bandwidth to the country, although it likely carries the
bulk of traffic to the country.

operationally, there are a number of jurisdictions which filter content
and connectivity on a variety of basis.

adjusting the BGP announcements is a fairly quick and sure way to hobble
connectivity to specific content.  although, it is quickly bypassed by
shifting the content to other addresses and domain names.

i'm sure that this was an accidental leakage, and that appropriate corrections
were/are taken in due course.
