Cogent Communications told its Russian customers on Friday it's disconnected its high-capacity internet service because of Russia's invasion of Ukraine and the resulting economic punishment much of the rest of the world has begun.
"In light of the unwarranted and unprovoked invasion of Ukraine, Cogent is terminating all of your services effective at 5 PM GMT on March 4, 2022," the US company said in an email to customers, according to network monitoring and analysis firm Kentik. "The economic sanctions put in place as a result of the invasion and the increasingly uncertain security situation make it impossible for Cogent to continue to provide you with service."
