5/24/22, 7:45 PM Myanmar: Data on internet blocks and internet outages following military coup | OONI Source: Internet Outage Detection and Analysis (IODA), BGP Signals for MPT (AS9988), Mytel (AS136255), Ooredoo (AS132167), Telenor (AS133385), and YTP (AS18399). The nightly Internet outages begin at 18:30 UTC and end at 02:30 UTC for all these networks, suggesting high levels of coordination and automation. https://ioda.caida.org/ioda/dashboard#view=inspect&entity=asn/9988&lastView=overview&from=1613217600&unti https://ioda.caida.org/ioda/dashboard#view=inspect&entity=asn/136255&lastView=overview&from=1613217600&un https://ioda.caida.org/ioda/dashboard#view=inspect&entity=asn/132167&lastView=overview&from=1613217600&un https://ioda.caida.org/ioda/dashboard#view=inspect&entity=asn/133385&lastView=overview&from=1613217600&un https://ioda.caida.org/ioda/dashboard#view=inspect&entity=asn/18399&lastView=overview&from=1613217600&unt All of these data sources on the nightly internet outages corroborate what locals in Myanmar have been reporting, as well as what has already been reported quite extensively by the international media. Conclusion As the political environment in Myanmar changed (following the military coup on 1st February 2021), internet controls in the country increased. Last year, multiple websites (including a few ethnic media websites reporting on the situation in Rakhine) were blocked, and their blocking appears to be ongoing. We also observe the ongoing blocking of www.justiceformyanmar.org (an activist campaign which aims to pressure businesses and investors around the world to divest from Myanmar military businesses), and we recently detected the blocking of COVID-19 site (coronavirus.app) as well. But following the February 2021 military coup, the scale of internet censorship in Myanmar has become quite unprecedented. In summary, we now see: Social media blocks. Access to Facebook, Facebook Messenger, WhatsApp, Instagram, and Twitter appears to be blocked on multiple networks in Myanmar since early February 2021. Wikipedia block. Access to www.wikipedia.org appears to have been blocked on several networks in Myanmar (primarily seen from 20th February 2021 onwards). Circumvention tool sites blocked. Access to several circumvention tool websites (such as protonvpn.com and www.tunnelbear.com) appears to have been blocked on some networks in Myanmar in February 2021. Nightly internet outages. The first internet disruption was observed in the early hours of 1st February 2021 (on the day of the military coup), followed by a second, higher impact internet outage on 6th February 2021 (which lasted for almost 30 hours). As of 15th February 2021, Myanmar https://ooni.org/post/2021-myanmar-internet-blocks-and-outages/ 15/16
