(Natural News) If you tried to visit Natural News and several of our affiliated websites including popular search engine GoodGopher.com over the past 48-plus hours and were unsuccessful, you certainly were not alone. That's because we were hit with a highly sophisticated DDoS — direct denial of service — attack that our founding editor Mike Adams, the Health Ranger, believes was directed by a U.S. government agency.

In an interview, Adams explained that the offensive was very likely generated by the Centers for Disease Control and Prevention (CDC) regarding a White House petition seeking a moratorium on childhood vaccines.

The petition — located here — notes:

American children are in crisis with an explosion of once-rare neurological problems like autism and seizures.

Recent scientific evidence has shown massive contamination of vaccines with unsuspected chemical and biological agents. Other evidence shows dramatic differences in health outcomes between vaccinated and un-vaccinated children. 

The DDoS attack was at "a very high level," Adams said, adding that its level of sophistication means "it must have cost somebody a lot of money" to coordinate and carry out.

"It seems the attack has been linked to the White House petition story," he noted, adding that the petition link went down as well, but has since been reinstated.

"Somebody's spending a lot of money because" the attack "lasted for more than 12 hours. At one point, there were over a quarter of a million connection requests per second." That's "a level of attack that requires a tremendous amount of coordination and funding."

"We suspect that the CDC is using taxpayer money to fund a cyber warfare campaign against vaccine truth web sites" like Natural News, Adams continued. "We already know the CDC is using taxpayer money to run vaccine propaganda, to pay for pro-vaccine messages in pop culture" like movies, TV shows, and other entertainment venues.

The agency also has a history of conducting and publishing its own vaccine-promotion research, then getting it into publication.
