Government Spokesman Maj General Sansern Kaewkamnerd told Nation TV that the collapse of Information and Communications Technology Ministry website was possibly caused by those who wanted to express their opposition against the single gateway initiative i
"I have no information about that but I guess that the problem could happen when many people entered the site simultaneously. It's like a symbol [of protest]," he said.
He insisted the single gateway initiative was just in a study process and not implement yet.
Earlier in the evening, a campaign has been widely shared among Thai Internet users, urging them to launch the DDoS (denial of service) attack against the ICT website (www.mict.go.th) at 10 pm.
The campaign urged Internet users to go to the address and refresh the page continuously by pressing F5 on the keyboard ceaselessly.
The attack was urged to retaliate against the government's plan to use the single Internet gateway measure.
The website was down since 7 pm.
The campaign said they would attack a new target after the ICT website was brought down.
But Group Capt Somsak Khaosuwan, deputy permanent secretary of ICT, denied the ICT website had collapsed. He said the site's connection was slow because of being overloaded with visitors.
He told The Nation that since there were many people entered the site at the same time, the existing network was unable to provide service for all of those who wanted to visit the site.
However, technicians of the ministry are fixing the system to resume the service, he said.
An IT expert, who asked not to be named said what happened to the ICT website actually fit into the DDoS as defined by Wikipedia as: "A distributed denial-of-service (DDoS) attack occurs when multiple systems flood the bandwidth or resources of a targeted system, usually one or more web servers. Such an attack is often the result of multiple compromised systems (for example a botnet) flooding the targeted system with traffic."
A source in ICT industry told The Nation that the ministry website faced manual DDoS attacks, which were carried out by the crowds, not by bots or computer codes.
“Flood DDoS attacked cannot be easily handled with any tools or devices,” said the source.
The source said a way to handle the attack with the distributed denial of service or DDoS is to increase bandwidth and increase numbers of [web] hosting.
It is be able to increase [website] bandwidth while offering the website’s service if the website’s server is located at the Internet Data Center.
If not, to increase bandwidth need to off the website while increasing the bandwidth. Another the way to handle the attack with DDoS is to increase numbers of web hosting with network load balancer that can be increase as maximum as numbers of LAN ports available.
Normally, the single host, by average, can handle around 50,000 request per second. It is not disclosed that how many web hosting of ICT Ministry’s website. If there are more [web] hosting, time to be downed is extended since there will be load balancer to balance and manage traffics.
The angry net users reportedly tried to flood the two other websites with overwhelming traffic after they successfully mounted an attack on the ICT site.
