Residents Express Distress
Amid the blackouts, Havana residents expressed growing distress over their daily survival and the inability to access basic services.
Self-employed social media community manager Meyboll Font described the severe impact of the outages on local neighborhoods.

Font noted that her neighborhood had been receiving only three to four hours of electricity daily before the total grid failure occurred.
Other residents in the capital expressed immediate concern over food preservation and basic cooking capabilities.

"We’re without power again," said Richard Valdés, 40. "Now we have no water, no gas, nothing until they restore it."
Many citizens expressed resignation regarding the systemic infrastructure issues.
"Oil hasn’t come in here for a while, and we have no way to solve the problem," said Mario Pedroso, a 33-year-old Havana resident.
"We have to resist, as we Cubans say. That’s all."
