The feud between the two countries, namely Ukraine and Russia, has weakened internet connectivity in the area around Kharkiv, the second-largest city.
Russia's attack on Ukraine has occurred since Wednesday night Eastern European time, crossing the country's northern, southern and eastern borders.
Sadly, as the conflict escalates, many civil society groups are increasingly concerned about a possible direct attack on the country's internet infrastructure.
Russia has previously been linked with DDoS attacks against Ukrainian government sites, using physical or cyber weapons to disable telecommunications infrastructure at the network level, further silencing Ukraine.
The Invasion has reduced internet connectivity in some parts of the country. Currently, the outage appears to be centered around Kharkiv, Ukraine's second-largest city.
The position of the city is about 25 miles from the Russian border. The Internet Outage Detection and Analysis Project (IODA) at Georgia Tech reports that the partial outage started just before midnight on February 23-24.
The outage affected internet service provider Triolan, which serves several cities and other areas in Ukraine, including Kharkiv.
According to internet outage tracker NetBlocks, Triolan users have reported a loss of fixed-line internet service while the smartphone continues to work.
A message was seen on the Triolan website (02/24), notifying customers of some cities' partial or complete lack of access.
The Verge report from the company's official Telegram channel claims that most of the service has been restored. However, responses indicate that many customers are still experiencing network outages.
The Triola update also notes that DNS servers that send requests to human-readable URLs are experiencing unstable operations in some areas.
Customers are instructed to connect using the 1.1.1.1 or 8.8.8.8 service, public DNS resolvers provided by Cloudflare and Google.
A Cloudflare spokesperson reported that traffic monitoring showed Ukrainian internet services were primarily operational, but connections from Kharkiv were interrupted.
