ETECSA announced this Wednesday the restoration of services for Nauta and Transfermóvil, which had been interrupted for two days due to the electricity crisis affecting Cuba. The telecommunications company published the statement on its official account on social media X without providing technical details about the incident.
"We inform you that, following actions carried out among several institutions, the services affected on October 5 have been restored. Our specialists are continuing to assess the performance of the various systems and platforms," the company stated in its announcement.
The outages began on Monday when power cuts disabled ETECSA's technological systems and equipment. At that time, the company acknowledged that the interruption affected Nauta browsing, electronic payments via Transfermóvil, and the management of associated services, although it clarified that mobile data remained operational. It did not provide an estimated date for restoration nor specified how many provinces or users were affected.
The electrical context during those days was particularly severe. Havana reported 62 affected circuits and a deficit of 167 MW early on Monday morning, a figure that worsened hours later. On Tuesday, the available generation of the National Electric System barely reached 1,223 MW against a demand of 3,050 MW, resulting in a deficit of 1,827 MW.
This interruption is not an isolated incident. At least 23 of the last 30 days prior to Monday exceeded the threshold of 2,000 MW of impact on the national electrical grid, making power outages a constant issue that directly affects telecommunications.
The most serious incident of the year occurred on September 18, when the eighth national blackout rendered over 80% of radio base sites and nearly 70% of telecommunications cabinets inoperative, resulting in a 58% drop in internet traffic. In light of this collapse, ETECSA halted the expansion of its access network to focus resources on the installation of photovoltaic panels.
Transfermóvil had already gone out of service on September 2 due to SMS failures, and Nauta experienced issues in August following a fiber optic cut. The payment platform exceeds 5.4 million users and accounts for over 70% of the country's electronic transactions, so its interruption directly impacts the daily lives of millions of Cubans who rely on it to pay for basic services and manage their finances.
The company itself acknowledged in September that power outages put telecommunications in the country in a difficult position: “It is not feasible to continue investing to expand the access network if there is no capacity to support the telecommunications infrastructure with energy.”
Meanwhile, ETECSA has accumulated around 77,000 reports of interrupted fixed services without announcing any compensation for users, despite the tariff increase implemented in May 2025.
