On 19 March 2006, date of the presidential elections in Belarus, the major online independent news resources (svaboda.org, charter97.org, belapan.com, ucpb.org, naviny.by, kozylin.com, zubr-belarus.com) were the targets of various types of attacks.
The Website of "Nasha Niva" newspaper was not available from Belarus on 18 March on the Internet. Other problems were spotted in accessing tut.by, a major Belarusian portal with about 60 000 visitors/day.
Also, Milinkievich's (candidate from Unified Democratic Forces) official website was unavailable for 2 days starting on 19 March. According with website administrators, they lost control over the server.
Charter97 press-centre websites were permanently attacked. Authorities not only used their usual techniques (IP address blocking, massive DoS attacks) but Internet filtering as well. As a result a number of websites were unavailable from Belarus.
Belarus has a large system put in place in order to restrict Internet access and control unwanted content. Some laws make it illegal to publish information that is contrary to state interests. ISPs from Belarus have to buy their connectivity from the telecom monopoly company.
