“We are doing everything possible to resolve the technical issues as quickly as possible,” the company said in a statement responding to these concerns.

The company did not say whether this disruption was related to a recent Dec. 12 cyberattack on the operator’s network, which took down Kyivstar connectivity for several days, including telecom and internet services.

Russian hackers associated with the Suntsepiok group, a unit associated with Russian military intelligence (GRU), claimed responsibility for the attack.
