On 5th of December, we visited Datacube datacenter in Petržálka, Bratislava. We saw a state-of-the-art category 3 datacenter, including backup diesel generators, fire suppression systems and advanced water-cooling systems. Most prominent datacenter clients include AT&T, Deutsche Telekom, Slovak e-vignette, Slovensko.sk digital services, EU and NATO. Overall, the experience was highly educational, and we are eager to visit again.
