March 11th, 2022: Telecommunications Outages in Ukraine

Reported from Data Center Dynamics, outages were identified to Ukraine's telecoms operator, Ukrtelecom and internet service provider (ISP), Triolan. An investigation of the activity by Doug Madory, the director of internet analysis at Kentik, identified the disruption in service from Ukrtelecom resulted in an approximate, 40 minute outage period. The impact to Triolan is more severe as the ISP, is experiencing an excess of 12 hours for its an outage period. The attack against Triolan has also been reported by Forbes, identifying from sources within the company that the cause of the outage was due to a "cyberattack." The cyberattack against Triolan appears to have started on March 9th, 2022 when outages were first experienced, with the identified issue shared as "attackers reset the settings to the factory level [with impact to] key nodes of the network.” Partial service has been restored as Triolan restored "70% of those nodes in Kyiv, Kharkiv, Dnipro, Poltava, Odesa, Rivne and Zaporizhia." The cyberattack against Triolan is not the first as a post on the company’s Telegram page reveals a hack on February 24 as well.
