The widespread blackout that began early Wednesday morning in Cuba has caused a massive loss of Internet connectivity.

The independent group Diktyon, which monitors the Internet situation on the Island, shared a graph on its Twitter account showing that at 2:08 AM, when the National Electric System (SEN) was disconnected, there was a sharp drop in the volume of traffic in the country's cyberspace.

Five hours later, the amount of bytes transferred to and from Cuba remains quite low.

"It has remained, since the last disconnection of the national electricity grid began, between 39 and 50 percent of the value for this day, at the same hours, compared to the previous week," the information specifies.

For its part, the state telecommunications monopoly ETECSA provided a report on the impact of the mobile service following the system collapse.

At 1:00 PM, the national impact was 53%. The most affected provinces are Camagüey, with 63%, and Havana, with 60%.

"The company stated on Twitter, 'As power is restored, service availability will increase.'"
