Alphabet's Loon, started in 2016, uses solar-powered balloons as Wi-Fi carriers to deliver signals from up in the air.
The company said Thursday it's using its balloons to provide LTE to areas of Peru impacted by a magnitude 8.0 earthquake that hit earlier this week.
Loon was able to quickly respond to the situation because it had already been active in Peru.
The company says it's spent the last few months negotiating a commercial contract with telecommunications company Telefónica to provide mobile internet access to areas around the country, especially those that are remote.
In the last month, Loon began installing infrastructure and testing the balloons.
When the earthquake hit, the Peru government and Telefónica asked Loon to send balloons to the impacted area.
