Internet disrupted in Myanmar amid apparent military uprising

Network data from the NetBlocks Internet Observatory indicate the onset of widespread internet disruptions in Myanmar on Sunday 31 January 2021 (UTC) amid reports of a military uprising and the detention of political leaders including Aung San Suu Kyi.

The telecommunication disruptions beginning approximately 3:00 a.m. Monday morning local time have significant subnational impact including the capital and are likely to limit coverage of events as they take place. Continuing disconnections have been monitored with national connectivity falling initially to 75% and subsequently 50% of ordinary levels by 8:00 a.m. local time.

Technical data show cuts affecting multiple network operators including state-owned Myanma Posts and Telecommunications (MPT) and international operator Telenor, with preliminary findings indicating a centrally ordered mechanism of disruption targeting cellular and some fixed-line services, progressing over time as operators comply.

Findings are corroborated by users on the ground and journalists who describe being unable to get online and a simultaneous loss telephone connectivity. Geographic indicators from the observatory suggest that outlying regions of the country and technical infrastructure may be less affected.

The incident has been described by sources as a military coup following an escalating standoff with the country’s civilian leadership, days after military chief General Min Aung Hlaing stated that the country’s constitution could be revoked.

Update: Some cellular connectivity has been restored as of noon Monday, but many users remain offline and it remains unclear whether the partial restoration will be sustained:

Update: 3 February 2021 UTC: Facebook, Instagram, Messenger and some WhatsApp servers are now restricted in Myanmar on state-run internet provider MPT. Meanwhile, metrics indicate that the restrictions are also coming into place on Telenor and other providers.

Real-time metrics show selective filtering in place limiting usage of Facebook’s products even as basic network connectivity is restored. Users report having to resort to VPN tools that can circumvent internet censorship to access the impacted online platforms:

As of evening Thursday 4 February local time, technical data from the NetBlocks Internet Observatory confirm Facebook is restricted on most major providers. Findings show variations in implementation of the military ban, with some companies restricting access the Facebook website and others blocking the wider suite of Facebook products and mobile applications:

Update: Network data confirm the restriction of Twitter on Myanmar’s leading network operators as of 10:00 p.m local time, Friday 5 February. The new restrictions follow the blocking of the country’s most popular social media platform Facebook earlier this week.

Metrics indicate that operators MPT, Mytel, Welink, 5BB and Frontiir were first to be impacted beginning approximately 10:00 p.m. local time, with Telenor losing Twitter service some hours later:

Update: Saturday, 6 February 2021: Myanmar is entering a second nation-scale internet blackout as of approximately 10:00 a.m. Saturday local time. Real-time network data show national connectivity falling to 54% of ordinary levels as users on major network providers report difficultly getting online.

Worsening disruption has been observed through afternoon, with connectivity collapsing to just 16% of ordinary levels by 2:00 p.m. local time, attributed to a combination of technical restrictions as well as apparent power cuts.

The incident comes amid a wave of protests against the military uprising. Metrics from the observatory indicate similar magnitude to disruptions tracked during the initial military uprising, with high impact to cellular networks:

The internet shutdown has continued into Sunday. As crowds gather for a second day of anti-coup protests, real-time network data show the country remains in the midst of a nation-scale internet blackout with national connectivity flatlining at just 14% of ordinary levels.

A partial restoration of network connectivity was confirmed from 2 p.m. although metrics indicated that social media platforms remained restricted for most users. This has progressed toward a more complete recovery by midnight.

Fact checks

Smart TVs across Myanmar started displaying nonsensical Chinese letters from 11 February 2021, stoking fears of a foreign incursion at a time when communications were increasingly disrupted.

However, the phenomenon is a technical glitch caused by the escalation of recent platform restrictions in Myanmar. A NetBlocks investigation has identified the phenomenon to be a side effect of the restriction of Google’s static CDN servers causing Web Font icon load failures in application user interfaces.

The fallback to meaningless Chinese characters on LG and Samsung smart televisions is a known issue, also observed during technical outages in the U.S. and other territories.

NetBlocks diffscans, which map the IP address space of a country in real time, show internet connectivity levels and corresponding outages. Purposeful internet outages generally have a distinct network pattern used by NetBlocks to determine and attribute the root cause of an outage, a process known as attribution which follows detection and classification stages.

Internet performance and service reachability are determined via NetBlocks web probe privacy-preserving analytics. Each measurement consists of latency round trip time, outage type and autonomous system number aggregated in real-time to assess service availability and latency in a given country. Network providers and locations are enumerated as vantage point pairs. The root cause of a service outage may be additionally corroborated by means of traffic analysis and manual testing as detailed in the report.
