The fire knocked out power to the MiroHost data center.

Yesterday afternoon, many leading Ukrainian internet sites were down. Among them were Ukrainska Pravda, Rozetka.ua, and I.UA.

The website access issues were caused by a serious power outage in the MiroHost data center. Both servers were down.

The exact cause of the failure of the equipment, which is designed to ensure uninterruptible power supply, has not yet been established.

The data center's power supply problems were caused by a power outage on the subway lines caused by a fire.

The company noted that UA-IX operations were resumed within 20 minutes of the outage.
