![]() ![]() “Russian sites have also shown evidence of distressed network conditions indicative of DDoS attacks, as well as behavior consistent with route filtering, firewalling of traffic and, in some cases, cloud-based DDoS mitigation,” company researchers wrote. Much of the disruption-coming in the form of dropped traffic that often reached a 100 percent loss of packets-was the result of distributed denial-of-service attacks or attempts by Russian networks to fend off the attacks. ![]() ThousandEyes said that while wholesale traffic going into and out of Russia is currently normal, traffic to select Russian sites-both from inside and outside the country-was spotty. It’s not clear how that termination will affect transit service for the country. The ThousandEyes post was published before the London Internet Exchange-one of the Internet’s biggest exchanges for networks around the world to swap or “peer” traffic with each other-would stop routing for Rostelecom and MegaFon, Russia’s No. “We have not yet experienced network disruptions, but given the increasingly uncertain environment and the heightened risk of state action, we took this move to ensure the security of our and our customers’ networks, as well as the ongoing integrity of the global Internet.” “We decided to disconnect the network due to increased security risk inside Russia,” Mark Molzen, the company's global issues director, told CNN. Lumen cited a similar rationale for its limited move. “We felt that the downside of having the possibility that these connections could be used offensively outweighed the negative of terminating some services,” Cogent CEO Dave Schaeffer said. ![]() Russian businesses that rely on Cogent’s network outside the country through non-Russian state providers remain unaffected. Cogent’s CEO told the news network that his company had limited its action to around 25 customers incorporated in Russia and directly on Russian networks. Advertisementīoth Lumen and Cogent told CNN on Friday that they were trying to balance the need to prevent their networks from carrying cyberattacks backed by Russia with their convictions for a free and open Internet. Another reason is that both Lumen and Cogent continue to provide transit services to the outposts of major Russian ISPs as long as those outposts aren’t located inside Russia. One is that the exit of a single transit provider from a country the size of Russia-or two providers, in this case-doesn’t have enough of an impact to degrade overall service. Network metrics show that connectivity continues as it has historically. Some people predicted Russia might even find itself effectively severed from the global Internet.īut so far, that hasn’t happened, researchers from network intelligence firm ThousandEyes said on Friday. “This reduction in bandwidth may lead to congestion as the remaining international carriers try to pick up the slack,” he added. He and others said the move would constrain the overall amount of bandwidth coming into and out of Russia. Still kickingĪ transit provider disconnecting its customers in a country as big as Russia has never happened before, Doug Madory, the director of Internet analysis at network analytics company Kentik, said earlier this week. The other was Cogent, one of the biggest Internet backbone carriers in the world. One was Lumen, the top Internet transit provider to Russia. Earlier this week, Russian ISPs saw the exit of two of their biggest providers. These so-called transit providers route massive amounts of traffic from one ISP or backbone to another. Just as ISPs provide links connecting individuals or organizations to the Internet, backbone services are the service providers that connect ISPs in one part of the world with ISPs elsewhere. Rumors of Russian Internet services degrading have been greatly exaggerated, despite unprecedented announcements recently from two of the world’s biggest backbone providers that they were exiting the country following its invasion of Ukraine. ![]()
