ETECSA acknowledged this Tuesday a widespread deterioration of its mobile network across Cuba, directly attributed to the power outage that has left the country without electricity since Monday.
The telecommunications company of the regime published a brief official information note on Facebook, in which it acknowledged that "due to electrical failures and difficulties with the generators that support the network, there has been an increase in mobile service disruptions."
Finally, ETECSA merely stated that its specialists "work continuously" to ensure network availability, without providing details about the actual extent of the affected areas or the timeline for resolving the issue.
The statement comes nearly 24 hours after Cuba experienced a complete disconnection of the National Electric System on July 6, marking the seventh total blackout in 18 months and the third so far in 2026.
This Tuesday, Cuba remained engulfed in a blackout nearly 24 hours later, with the national electrical system yet to fully recover.
The dependency of the telecommunications network on the electrical supply is a structural problem that ETECSA has acknowledged.
Last June, a company official publicly admitted that "it is not possible to keep the telecommunications infrastructure operational for more than 24 hours without power from the grid."
The official data from the company illustrate the magnitude of the problem: power outages render approximately 47.5% of mobile base stations and 56.5% of telecommunications cabinets non-functional on a national scale.
Approximately 450 radio bases are disrupted daily due to the prolonged use of generators, which accumulate mechanical failures and fuel depletion.
The situation is particularly critical in provinces like Sancti Spíritus, where only 21 out of the 70 telephone exchanges have backup generators, leaving over 288,000 mobile lines vulnerable.
A similar situation occurred in March of this year, when a malfunction in ETECSA's generator in Cárdenas left that city without mobile and landline signals.
As a temporary measure, ETECSA has begun installing solar panels in some areas, although with a limited autonomy of between seven and eight hours, which is insufficient to sustain the network during prolonged blackouts like the current one.
This Tuesday, the United States Embassy in Havana issued its seventh security alert of the year, warning that the Cuban electricity grid "is becoming increasingly unstable."
At the same time, since July 2, there have been recorded protests and spontaneous demonstrations in Havana and Santiago de Cuba, which the regime has responded to with police operations.
