A group called Sinar Project claims Telekom Malaysia and Maxis have blocked access to election result site live.undi.info on GE14 Polling Day.
According to Sinar Project:
Sites such as Bersih.org, political party websites and official elections page were temporarily inaccessible intermittently on different networks early on the day of polling, but many were due to network timeouts. This seems to indicated either heavy traffic to the websites or other network related issues.
Key sites that would have affected voters, such as official service to check location of assigned polling booths (pengundi.spr.gov.my) was accessible throughout polling day.
Blocking through DNS hijacking of independent election results site
Network interference data by Open Observatory showed that for critical period of #GE14 election result updates in late evening, TMNet & Maxis blocked Malaysiakini’s live.undi.info via DNS hijacking. On recorded instances, users on these networks using ISP provided DNS service would be redirected to 184.108.40.206 the ip address used to serve the standard government legal notice that a site has been blocked. While there were reports by the public of screenshots of the notice, for the measurement data collected the tests could only get connection errors from the redirected server.
First measured time of censorship was 9:55pm on TMNet shortly before official election updates from Elections Commission and other news sources stopped from around 11pm.
This would indicated that there was a possible attempt by caretaker government to censor election results from independent sources such as independent news media.
At the moment, it is unclear why the ISPs blocked access to the site.
