A recent blackout across the Iberian Peninsula highlights the vulnerabilities within internet connectivity; while large data centers have backup power, intermediate equipment crucial for connection is exposed to outages. Arturo Azcorra from Imdea Networks notes that this equipment's failure could sever service continuity. Vodafone reports a partial functioning network due to generators, urging customers to use services wisely. However, reliance on Wi-Fi access poses challenges, especially outdoors, as connectivity largely depends on electricity availability at critical locations and infrastructure support.
The internet can survive a few hours without power, but not for long. Large data centers are protected by their own clusters that can operate indefinitely.
Even if large data centers survive, without this intermediate equipment, the connection would not be possible: It's as if the central nervous system worked, but the peripheral system did not.
Vodafone has reported that its network is currently 70% active, thanks to backup generators, but its operation will depend on how long the blackout lasts.
On the street, base stations rooftop antennas don't work unless they're near critical locations and have special equipment to generate electricity.
