On the afternoon of Saturday 25 November, internet users reported disruptions affecting key social media platforms amid protests. The present investigation seeks to provide an early determination of the extent of those restrictions.Between 16:00 pm and11:00pm on 25th November 2017 , measurements from 121 unique vantage points distributed through 16 ASNs (Autonomous System Numbers) covering major cities and regions in Pakistan were collected, geolocated and anonymised via the NetBlocks web probe measurement network. Twitter and Facebook are currently restricted with mobile operators Mobilink, Zong, Telenor, Ufone and fixed providers PTCL, Witribe, Zong and Cybernet. Our data indicates that YouTube restrictions are only partially implemented, suggesting that many internet users in Pakistan will still be able to access the video streaming service. Availability of other services has not yet been investigated. A control set of international news websites remained reachable, indicating that the restrictions are targeted to suppress social media coverage of the unrest. The restrictions remain in effect at the time of writing.
