Question

In various applications, the network sometimes becomes unavailable, which leads to related problems.
The simplest experiment: ping ya.ru usually runs fine, but sometimes says ping: unknown host ya.ru.
At the same time, the same ping ya.ru launched in the neighboring terminal continues to work quietly.
