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.
Update: Internet connectivity in #Myanmar has fallen to 50% of ordinary levels as of 8:00 a.m. local time amid an apparent military coup and the detention of civilian leaders; pattern of disruption indicates centrally issued telecoms blackout order 📵

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: Internet service in #Myanmar has been partially restored as of midday with users learning of a new political landscape and year-long state of emergency declared by the military; network data show connectivity back up to 75% of ordinary levels 📈

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.f
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:
Update: Facebook products are now restricted on multiple internet providers in #Myanmar as operators comply with an apparent blocking order.

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:
Update: A near-total internet shutdown is now in effect in #Myanmar.
Network data show a collapse of connectivity to 16% of ordinary levels from ~2 pm local time 📉
The information blackout is likely to severely limit coverage of anti-coup protests 📵
— NetBlocks (@netblocks) February 6, 2021
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.
ℹ️ Update: Partial restoration of internet connectivity confirmed in #Myanmar from ~2 pm local time on multiple providers following information blackout. However:
➡️ It remains unclear if restoration will be sustained
➡️ Social media remain blocked

Blocking of Wikipedia in Myanmar on 18 February 2021
From Thursday morning, the Wikipedia online encyclopedia has been added to the growing list of platforms restricted on major network operators upon order of the military junta.
NeBlocks metrics indicate that all language editions, as well as associated websites including Wikidata and the Wikimedia Foundation’s corporate presence are restricted on most of the country’s major network providers. The restrictions are targeted and are distinct from general outages and disruptions tracked during the reporting period.
While no basis has been supplied by authorities, the restriction of Wikipedia comes as the military government outlaws the use of certain words in reference to the coup d’état and opposition movement. At the time of writing there are also indications of an “edit war” on the Wikipedia article for military ruler General Min Aung Hlaing in relation to his title and career.
Confirmed: #Myanmar has blocked all language editions of the Wikipedia online encyclopedia, part of a widening post-coup internet censorship regime imposed by the military junta 📚
Network data show restriction in effect on major providers.

Wednesday, 28 April 2021: Fixed-line internet restrictions eased after 72 nights
Fiber/FTTH internet connectivity restrictions have been eased in Myanmar on Wednesday following 72 consecutive nights of near-total shutdowns. The move marks a possible end to the scheduled curfew-style nightly restrictions imposed by the military shortly after the February coup.
However, the easing will provide little respite for most users around the country who are reliant on mobile data services, which have been cut around the clock 44 days and remain so. Online platforms and services including but not limited to social media and messaging applications are also still heavily restricted.
ℹ️ Live network data indicate fixed-line/fiber internet service remains largely available in #Myanmar after 1 am Wednesday, the first time after 72 nights of near-total shutdowns. However mobile data remains cut and platforms are heavily restricted.

Smart TVs across Myanmar started displaying nonsensical Chinese letters from around 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.
ℹ️ Fact Check: TVs across #Myanmar started displaying Chinese letters from 11 February stoking fears of a foreign incursion.
However, analysis reveals it to be a side effect of the restriction of Google's static CDN causing Web Font icon load failures.

NetBlocks diffscans, which map the IP address space of a country in real time, show internet connectivity levels and corresponding outages. Purposeful internet outages may 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.
